Main scientific achievements

All of my work is motivated by developing basic science for materials technologies (nuclear and non nuclear).

1964-1977: Interfacial Diffusion

Grain-boundary (GB) diffusion was known to have a deleterious effect in the early nuclear fuel cladding (dispersion strengthened Mg) and, later, grain boundary electro migration was acknowledged to have a key role in the failure of micro-conductors in supercomputers. In this context, I measured two basic characteristics of grain boundary diffusion in a simple model metal, silver: the activation volume1 and the effective valence4, which measures the proportionality between the fluxes of atoms and of electrical charges. The measurements were performed on bycrystals, using radiotracer techniques, which implied very low activity measurements. The activation volume we measured pointed to a vacancy diffusion mechanism at the grain boundary (an unconventional idea in those days): this result got confirmed 20 years later in U. of Münster, in Germany. The effective valence we found was of the same sign as in the bulk, which ruled out some speculations in the literature on the possibility for hole conduction at the GB’s.

The GB diffusion models used at that time were very rough (a high diffusivity slab of finite thickness), while electron microscopy and field ion microscopy in metals were revealing undisturbed crystalline atomic packing up to the contact surface between the adjacent grains, in metals. For this reason, we proposed, together with Dr. P. Benoist (Wigner medal 1996), a lattice model for surface and GB diffusion, where the fast diffusion paths are confined to the contact surface between the two crystals9. We could thus specify the physical meaning of the parameters used in the classical models.

I later extended the formalism of GB diffusion to alloys17 and to phase boundaries10, two cases of practical relevance, where interfacial equilibrium conditions must be handled with care.

Other work included measuring the activation volume for Na diffusion in NaCl (at U of I Urbana, Pr. D. Lazarus), confirming a positive relaxation volume of the Schotky pair6, at variance with the best theoretical values of those days (the use of a linear approximation for the displacement to force ratio was at the origin of the error).

I also reformulated the rate of decay of capillarity waves, in the limit where adatom emission / absorption at surface steps is the rate controlling process, rather than surface diffusion from step to step (as postulated by Mullins in his famous work)21.

1969-1984: High temperature irradiation effects

In the late 60’s British scientists discovered irradiation induced swelling of stainless steel used as a cladding material in the Donrey fast reactor. The latter discovery triggered a worldwide interest. Swelling still raises problems in some core components of PWR’s. As is often the case in nuclear technologies, this swelling phenomenon challenged materials science and engineering, since no macroscopic theory can account for it: one must link the atomic scale, where nuclear collisions are well described, to the time evolution of the strain tensor, from which engineers can handle structural mechanics computations. This, I found very appealing.

My first contribution in this field together with Jean-Paul Poirier, dealt with the plastic deformation in metals under irradiation: based on simple defect balances we pointed, for the first time, to the possibility of a creep rate proportional to square of the shear stress2.

I then focused on more generic aspects of materials under high temperature irradiation, i.e. temperatures where the irradiation produced point defects can migrate distances large enough for a (quasi) stationary defect population to prevail in the solid. Such materials can be viewed as an open system sustained by external forcing (injection of defects) in some stationary state, the stability of which is not governed by thermodynamical potentials (an active field of research in the 70’s).

My first attempt along this line, dealt with the formation of void- (or other defect clusters) lattices13. According to this work, the latter appeared as a result of the spatial instability of the stationary uniform defect population, provided the defect-defect physical interaction is taken into account in the coupled reaction-diffusion equations, which govern time evolution of the vacancy and interstitial concentration fields. The model predicted that such a patterning would occur beyond some critical irradiation flux threshold, which depends on temperature, a prediction, which was confirmed by A. Barbu in his PhD thesis work.

This finding supported a suggestion by Adda et al. that depending on the irradiation flux and temperature, diffusion under irradiation might drive the material in opposite directions

(order/disorder, dissolution/precipitation, amorphization/crystallization…). A.Barbu22, 31 showed that such is indeed the case for irradiation induce precipitation in undersaturated solid solutions (Ni-Si).

My model also gave a general argument to account for irradiation-induced instability of undersaturated solid solutions28. Vacancy-interstitial mutual annealing introduces a weak coupling between the concentration fields of the solute and of the two types of defects: provided that the couplings between solute and defects fluxes is properly accounted for (“inverse Kirkendal effect”), the latter may destabilize the solid solution. Together with R. Cauvin26, 35, 36, 43, 54 we found evidence of such an effect in Al base solid solutions: the full spectrum of reaction to irradiation of many distinct solid solutions could be rationalized with the above argument, while constraint thermodynamics arguments failed to do so27. Potential consequences of the above mechanism on precipitate coarsening, or on the decomposition of INVAR alloys were explored together with K. Urban44 and C. Abromeit69, respectively.

The above formalism relied on the existence of stationary defect concentration fields, while the latter slowly evolve because of the microstructural evolution, which modifies the density of point defect sinks. Together with P. Valentin47, 51, 62, we modeled the coupled slow evolutions of various components of the microstructure, by eliminating the fast variables (defect concentration fields), which revealed some unexpected features, such as transient swelling, or a mechanism for the incubation of swelling, etc… One difficult point in modeling microstructures under irradiation deals with the evolution of the dislocation network. I addressed this problem very recently with D. Mordehai, paying special attention to the “coordinated climb” of neighboring dislocation segments231.

1984-1998 Driven alloys (for an overview, cf. ref. 166)

All the above models assumed that irradiation produces the point defects uniformly in space and time, while defects are produced in a correlated manner inside cascades, the size and density of which depends on the details of the slowing down of the irradiating particles. Moreover, cascades trigger local atomic mixing. From the theoretical viewpoint, cascades can be viewed as external noise imposed to the atomic configuration, with specific time and space correlation (at variance with thermal noise). A similar context prevails under sustained shear, such as during cyclic loading, materials processing by ball milling, etc… I suggested the analogy between the effects on phase stability, of irradiation and sustained shear in 198033.

Our first attempts failed to reveal any alteration of phase stability in Ni base binary solutions under high temperature cyclic loading, although an unexpected mechanism of bulk cavitation was found64. Several evidences of shear induced alteration of phase stability, such as precipitate dissolution in persistent slip bands or non-equilibrium segregations, were found by other groups, but were not rationalized with our ideas. Ball milling, on the other hand turned out to be more successful: we could define a “milling intensity” and demonstrate on model alloys (mainly FeAl and NixZry compounds) that under milling, the alloy achieves a state (ordered or disordered, crystalline or amorphous), which depends on the milling conditions (intensity and temperature). The analogy with irradiation effects was established137, 156. Advantage could be taken of this analogy in several studies of practical impact: optimizing the processing route of dispersed oxide compounds for electrical contact142 (among others), understanding the wear process of swift trains wheels217, and more recently optimizing drug processing by milling (M. Descamp, AIP Conference Proceedings, Volume 982, 2008,

53-61).

Developing the theory of driven alloys spread on a long period of time. The effect of “ballistic mixing”, i.e. the atomic mixing forced by nuclear collisions or dislocation glide during shearing, was first treated by simply superimposing forced atomic jumps to the thermally activated ones in a Cahn Hilliard type diffusion equation. The result was that the evolution of the solute concentration field is no more governed by the Gibbs free energy functional, but by a Lyapunov functional; the latter writes as the Gibbs free energy evaluated at an “effective temperature”, which depends on the ratio of the forced to the thermal atomic jump frequencies56. This idea yields qualitatively and sometimes quantitatively corrects results93.

We addressed the problem with increasing levels of sophistication:

  1. The state of the compound is defined by a uniform order parameter, the value of which is

governed by a the deterministic equation: single or multiple stationary states are found, depending on the forcing intensity and temperature, the local stability of which can be assessed74,121.

  1. The state of the compound is defined by a field of order parameter, the evolution of which

is governed by time dependant Gingsburg Landau equation. Special care had to be devoted to the expression of the kinetic coefficient under purely thermal conditions. I proposed a mean field approximation, which treats thermodynamics and kinetics at the same level of sophistication104. Based on this model, several problems could be addressed: coarsening under irradiation, kinetic pathways for precipitate dissolution, revealing the key role, on top of the reduce temperature, of the forcing intensity132, 143, 145. A practical application of the above technique dealt with irradiation induced interfacial segregations, a key issue in stress corrosion cracking of core components153, 184.

  1. The above technique could incorporate “inverse Kirkendal effect” on top of ballistic

mixing, yielding a unified treatment of both effects166.

  1. Keeping the homogeneous description, we addressed the stochastic aspect of the problem,

based on a Fokker Planck or Kubo equation85, 86, 90, 92, 98, 113. From these treatments, we could propose phase diagrams of dynamical-equilibrium under irradiation for model compounds (FeAl and Ni4Mo), several predictions of which have been later confirmed by experiment. E.g. the order disorder transition in FeAl, which is of second order shifts to first order under appropriate irradiation conditions147, the extension of the stability domain of ordered structures in Ni4Mo, varies with the size of the cascade, keeping the irradiation flux the same (experiments done in Argonne by Bellon et al. and in HMI by Banerjee et al.). Kinetic Monte Carlo simulations enriched the theoretical treatment150.

One of the applications of the above ideas about dynamical equilibria and microstructural evolution under irradiation dealt with the surprisingly good irradiation resistance of brazing of common use in PWR’s: the brittle Ni phosphides either amorphize or develop a dislocation network which makes them more ductile126!

On a more general level, the above results might be used to clarify the notions of dose, dose rate, flux, fluence, which are sometimes confusing in nuclear technologies: taking as a guide the medical meaning of a “dose” (the elementary ingestion of some drug), I proposed (up to now, without success) to name “elementary dose” the cascade (as defined by it’s size and density); the “dose rate” is the number of doses per unit time (and per unit quantity of matter) and the “integrated dose” is the integral of the latter. As we demonstrated and observed, the effect of a given irradiation depends on the three above parametersR5.

1994-... Configurational kinetics

As said above, driven alloys are such that two diffusion mechanisms are competing: a forced one, which is deduced from particle matter interaction, and the thermal one, which also operates in the absence of forcing. The reliability of modeling a kinetic pathway rests on the precision with which actual diffusion mechanisms are modeled. As we got involved in the field, most models were based on the kinetic Ising model, i.e. direct exchange diffusion mechanism and the same cohesive energy for the two components of the alloy, two features at variance of any metallurgical system: indeed, diffusion occurs because of vacancy jumps, and the alloy components have usually quite distinct cohesive energies, the latter scaling many of the vacancy properties (formation and migration energies). This was the driving force for revisiting the kinetic coefficient, which enters CahnHilliard’s diffusion equation. The expression we proposed, based on a broken bonds model, yields a unified description of configurational thermodynamics and kinetics, at the same level of sophistication104. Based on this model, we revisited many classical problems in solid-state kinetics, either using Kinetic Monte Carlo (KMC) simulations or various mean-field approximations:

  1. The realism of our KMC simulations has been assessed by comparing the precipitation of Ni3(Al,Cr) in a ternary model super alloy (NiAlCr) as observed by tomographic atom probe (TAP) and in our simulations191. In those days the improvement of the computing power, made it possible to run the real experiment and the virtual one on similar sample sizes. The quantitative and qualitative agreement between modeling and experiment was impressive. I improved the above study with D. Seidman, taking advantage of the recent explosion of the detection yield of Atom Probes. We could analyze a much greater number of precipitate nuclei, which revealed unexpected nuclei compositions and morphologies. The KMC simulations are based on first principle interatomic energies; the same parameters are used to compute the Onsager and diffusion matrices in the terminal solid solution. The origin of the unexpected features is demonstrated to be in the kinetic coupling among the fluxes of the alloy components, a coupling that is ignored by the classical models227, 232.

  2. More generic studies of kinetic pathways for the relaxation toward equilibrium were also

made, based on KMC simulations. We could identify the impact of the vacancy diffusion mechanism on various parameters such as the kinetic percolation limit, the Kolmogorov-Johnson-Mehl-Avrami exponent, or on qualitative features such as the uniform versus localized ordering process167, 173, 189, or the incubation time for precipitation193.

  1. Few problems with direct practical relevance could be addressed based on such a KMC technique: Cu precipitation in Fe160, formation of niobium carbides in low alloy steels, where the transient formation of a non-equilibrium iron carbide was predicted211.

The mean field approximation has been taken advantage of for revisiting basic problems of solidstate kinetics:

  1. Computing the Onsager matrix coefficients from the spectrum of defect (vacancy185 and

later self interstitial) jump frequencies; Studying the coupled relaxation of the order and composition fields (the classical model, which ignore that both fields relax because of the very same vacancy jumps, omit a coupling term)214, 157, 165; Expressing the interfacial transfer coefficient as a kinetic excess quantity129.

  1. Based on the same technique as the mean field model, we could study precipitation

complex alloy (Ag, In, Cd, Sn) undergoing transmutations, used as neutron absorber in PWR’s. Because the model used is based on a sound diffusion mechanism, the parameterization only required a small number of interdiffusion measurements175.

Studying precipitation phenomena, I focused on various aspects of the nucleation theories32, in particular on the free energy of a nucleus. Together with G. Jacucci (U. Trento, Italy) we used computer calorimetry to compute the latter in the Ising model (2 and 3 D), with a great level of accuracy: we could evaluate the correction to the capillarity approximation for small nuclei49, 57, 58. The free energies so computed can be used in cluster dynamics models for nucleation and growth. A direct assessment of the technique was done for the precipitation of AlZr, which was simulated using the KMC technique as described above, and using cluster dynamics parameterized as just described. The agreement is very good at least in the dilute case223. This research allowed to clarify some points of the classical nucleation theory224.

Miscellaneous

I did contribute to several studies which were underway in the laboratories I was the head of: metallurgy of quasi-crystals79, surface treatments by LASER heating70, interdiffusion induced amorphization83, 97, 115, kinetic pathways in epitaxial growth87, 88, 96,105, irradiation damage by swift ions63, 109…

The kinetics of morphological changes are fascinating, but difficult to phrase in general terms16: I addressed few questions such as the morphological stability of two phase super alloys with large precipitate volume fractions81, the rate of grain rotation across a grain boundary123, dewetting of a surface layer as a result of an interfacial reaction196, 202, 206, the incubation time for corrosion pitting82.

While the major part of my computer simulation work is based on Monte Carlo techniques, I devoted few years to using Molecular Dynamics to study atomistic aspects of crystalline plasticity:

dislocation pinning by small self interstitial clusters and the unpinning mechanisms in irradiated model Ni190, 199 and solute hardening in dilute Ni(Al) solutions219, 225. Both studies revealed features, which were not expected from continuum theories.

Managing research laboratories (1984-2002)

I had two very different experience of management: one at CNRS (1984-88), the other at CEASaclay (1989-2002).

At CNRS, the “Centre d'Études de Chimie Métallurgique” (Vitry sur Seine) was one of the earliest CNRS laboratories (50 years old), with about 60 scientists, 40 technical staff and 20 to 30 students. My main goal has been to stimulate a skill in modeling, in a community dominated by experimentalists, as well as forcing scientific communication among the teams.

At CEA, the Physical Metallurgy Laboratory (SRMP), which I was heading, underwent a deep renewal of people, because of the French retirement system. With 25 staff members, and 15 students, post-doc and visiting scientists, my main goal has been to keep and develop an expertise in the scientific basis for nuclear materials, at a time where such a field was temporarily outdated, and part of the team did work on problems like new routes of materials processing (mechanical alloying, electro deposition of High Tc superconductors...). Modeling from the atomic scale up has been the main achievement of that team; in particular, first-principle electronic structure computations were developed both for static and kinetic problems and provided the input parameters for atomic scale modeling. The cohabitation in the same small team of researches on very basic questions and researches on rather applied problems has been very stimulating, provided the communication among both sort of people could be maintained.

One of the major practical impacts of this expertise has been to introduce such techniques to the EDF research laboratory (EDF-Renardières, in the early 90’s).

Field of research:

Physical Metallurgy (experiments, theory and computer modeling from the atomic scale up)

  • Solid-state diffusion and diffusion-controlled kinetics;
  • Materials under irradiation (fundamentals of-): microstructural evolution, phase instability, non equilibrium segregations, plasticity; I introduced the concept of ‘‘Driven alloys’’ and applied it to phase stability under irradiation, under plastic straining, friction and wear; various applications to nuclear materials (swelling of steels, stability of brazed joints, metallurgy of neutron absorbing alloys in control rods…), mechanical alloying (finding new processing routes for special compounds), wear of swift trains wheels (French TGV);
  • Miscellaneous: crystal growth, corrosion, solute hardening, solid-state amorphyzation, metallurgy of an icosahedral phase, stability of INVAR alloys and of mixed phosphides.

This resulted in more than 240 publications and reports (list below)

Main scientific achievements

All of my work is motivated by developing basic science for materials technologies (nuclear and non nuclear).

1964-1977: Interfacial Diffusion

Grain-boundary (GB) diffusion was known to have a deleterious effect in the early nuclear fuel cladding (dispersion strengthened Mg) and, later, grain boundary electro migration was acknowledged to have a key role in the failure of micro-conductors in supercomputers. In this context, I measured two basic characteristics of grain boundary diffusion in a simple model metal, silver: the activation volume1 and the effective valence4, which measures the proportionality between the fluxes of atoms and of electrical charges. The measurements were performed on bycrystals, using radiotracer techniques, which implied very low activity measurements. The activation volume we measured pointed to a vacancy diffusion mechanism at the grain boundary (an unconventional idea in those days): this result got confirmed 20 years later in U. of Münster, in Germany. The effective valence we found was of the same sign as in the bulk, which ruled out some speculations in the literature on the possibility for hole conduction at the GB’s.

The GB diffusion models used at that time were very rough (a high diffusivity slab of finite thickness), while electron microscopy and field ion microscopy in metals were revealing undisturbed crystalline atomic packing up to the contact surface between the adjacent grains, in metals. For this reason, we proposed, together with Dr. P. Benoist (Wigner medal 1996), a lattice model for surface and GB diffusion, where the fast diffusion paths are confined to the contact surface between the two crystals9. We could thus specify the physical meaning of the parameters used in the classical models.

I later extended the formalism of GB diffusion to alloys17 and to phase boundaries10, two cases of practical relevance, where interfacial equilibrium conditions must be handled with care.

Other work included measuring the activation volume for Na diffusion in NaCl (at U of I Urbana, Pr. D. Lazarus), confirming a positive relaxation volume of the Schotky pair6, at variance with the best theoretical values of those days (the use of a linear approximation for the displacement to force ratio was at the origin of the error).

I also reformulated the rate of decay of capillarity waves, in the limit where adatom emission / absorption at surface steps is the rate controlling process, rather than surface diffusion from step to step (as postulated by Mullins in his famous work)21.

1969-1984: High temperature irradiation effects

In the late 60’s British scientists discovered irradiation induced swelling of stainless steel used as a cladding material in the Donrey fast reactor. The latter discovery triggered a worldwide interest. Swelling still raises problems in some core components of PWR’s. As is often the case in nuclear technologies, this swelling phenomenon challenged materials science and engineering, since no macroscopic theory can account for it: one must link the atomic scale, where nuclear collisions are well described, to the time evolution of the strain tensor, from which engineers can handle structural mechanics computations. This, I found very appealing.

My first contribution in this field together with Jean-Paul Poirier, dealt with the plastic deformation in metals under irradiation: based on simple defect balances we pointed, for the first time, to the possibility of a creep rate proportional to square of the shear stress2.

I then focused on more generic aspects of materials under high temperature irradiation, i.e. temperatures where the irradiation produced point defects can migrate distances large enough for a (quasi) stationary defect population to prevail in the solid. Such materials can be viewed as an open system sustained by external forcing (injection of defects) in some stationary state, the stability of which is not governed by thermodynamical potentials (an active field of research in the 70’s).

My first attempt along this line, dealt with the formation of void- (or other defect clusters) lattices13. According to this work, the latter appeared as a result of the spatial instability of the stationary uniform defect population, provided the defect-defect physical interaction is taken into account in the coupled reaction-diffusion equations, which govern time evolution of the vacancy and interstitial concentration fields. The model predicted that such a patterning would occur beyond some critical irradiation flux threshold, which depends on temperature, a prediction, which was confirmed by A. Barbu in his PhD thesis work.

This finding supported a suggestion by Adda et al. that depending on the irradiation flux and temperature, diffusion under irradiation might drive the material in opposite directions

(order/disorder, dissolution/precipitation, amorphization/crystallization…). A.Barbu22, 31 showed that such is indeed the case for irradiation induce precipitation in undersaturated solid solutions (Ni-Si).

My model also gave a general argument to account for irradiation-induced instability of undersaturated solid solutions28. Vacancy-interstitial mutual annealing introduces a weak coupling between the concentration fields of the solute and of the two types of defects: provided that the couplings between solute and defects fluxes is properly accounted for (“inverse Kirkendal effect”), the latter may destabilize the solid solution. Together with R. Cauvin26, 35, 36, 43, 54 we found evidence of such an effect in Al base solid solutions: the full spectrum of reaction to irradiation of many distinct solid solutions could be rationalized with the above argument, while constraint thermodynamics arguments failed to do so27. Potential consequences of the above mechanism on precipitate coarsening, or on the decomposition of INVAR alloys were explored together with K. Urban44 and C. Abromeit69, respectively.

The above formalism relied on the existence of stationary defect concentration fields, while the latter slowly evolve because of the microstructural evolution, which modifies the density of point defect sinks. Together with P. Valentin47, 51, 62, we modeled the coupled slow evolutions of various components of the microstructure, by eliminating the fast variables (defect concentration fields), which revealed some unexpected features, such as transient swelling, or a mechanism for the incubation of swelling, etc… One difficult point in modeling microstructures under irradiation deals with the evolution of the dislocation network. I addressed this problem very recently with D. Mordehai, paying special attention to the “coordinated climb” of neighboring dislocation segments231.

1984-1998 Driven alloys (for an overview, cf. ref. 166)

All the above models assumed that irradiation produces the point defects uniformly in space and time, while defects are produced in a correlated manner inside cascades, the size and density of which depends on the details of the slowing down of the irradiating particles. Moreover, cascades trigger local atomic mixing. From the theoretical viewpoint, cascades can be viewed as external noise imposed to the atomic configuration, with specific time and space correlation (at variance with thermal noise). A similar context prevails under sustained shear, such as during cyclic loading, materials processing by ball milling, etc… I suggested the analogy between the effects on phase stability, of irradiation and sustained shear in 198033.

Our first attempts failed to reveal any alteration of phase stability in Ni base binary solutions under high temperature cyclic loading, although an unexpected mechanism of bulk cavitation was found64. Several evidences of shear induced alteration of phase stability, such as precipitate dissolution in persistent slip bands or non-equilibrium segregations, were found by other groups, but were not rationalized with our ideas. Ball milling, on the other hand turned out to be more successful: we could define a “milling intensity” and demonstrate on model alloys (mainly FeAl and NixZry compounds) that under milling, the alloy achieves a state (ordered or disordered, crystalline or amorphous), which depends on the milling conditions (intensity and temperature). The analogy with irradiation effects was established137, 156. Advantage could be taken of this analogy in several studies of practical impact: optimizing the processing route of dispersed oxide compounds for electrical contact142 (among others), understanding the wear process of swift trains wheels217, and more recently optimizing drug processing by milling (M. Descamp, AIP Conference Proceedings, Volume 982, 2008,

53-61).

Developing the theory of driven alloys spread on a long period of time. The effect of “ballistic mixing”, i.e. the atomic mixing forced by nuclear collisions or dislocation glide during shearing, was first treated by simply superimposing forced atomic jumps to the thermally activated ones in a Cahn Hilliard type diffusion equation. The result was that the evolution of the solute concentration field is no more governed by the Gibbs free energy functional, but by a Lyapunov functional; the latter writes as the Gibbs free energy evaluated at an “effective temperature”, which depends on the ratio of the forced to the thermal atomic jump frequencies56. This idea yields qualitatively and sometimes quantitatively corrects results93.

We addressed the problem with increasing levels of sophistication:

  1. The state of the compound is defined by a uniform order parameter, the value of which is

governed by a the deterministic equation: single or multiple stationary states are found, depending on the forcing intensity and temperature, the local stability of which can be assessed74,121.

  1. The state of the compound is defined by a field of order parameter, the evolution of which

is governed by time dependant Gingsburg Landau equation. Special care had to be devoted to the expression of the kinetic coefficient under purely thermal conditions. I proposed a mean field approximation, which treats thermodynamics and kinetics at the same level of sophistication104. Based on this model, several problems could be addressed: coarsening under irradiation, kinetic pathways for precipitate dissolution, revealing the key role, on top of the reduce temperature, of the forcing intensity132, 143, 145. A practical application of the above technique dealt with irradiation induced interfacial segregations, a key issue in stress corrosion cracking of core components153, 184.

  1. The above technique could incorporate “inverse Kirkendal effect” on top of ballistic

mixing, yielding a unified treatment of both effects166.

  1. Keeping the homogeneous description, we addressed the stochastic aspect of the problem,

based on a Fokker Planck or Kubo equation85, 86, 90, 92, 98, 113. From these treatments, we could propose phase diagrams of dynamical-equilibrium under irradiation for model compounds (FeAl and Ni4Mo), several predictions of which have been later confirmed by experiment. E.g. the order disorder transition in FeAl, which is of second order shifts to first order under appropriate irradiation conditions147, the extension of the stability domain of ordered structures in Ni4Mo, varies with the size of the cascade, keeping the irradiation flux the same (experiments done in Argonne by Bellon et al. and in HMI by Banerjee et al.). Kinetic Monte Carlo simulations enriched the theoretical treatment150.

One of the applications of the above ideas about dynamical equilibria and microstructural evolution under irradiation dealt with the surprisingly good irradiation resistance of brazing of common use in PWR’s: the brittle Ni phosphides either amorphize or develop a dislocation network which makes them more ductile126!

On a more general level, the above results might be used to clarify the notions of dose, dose rate, flux, fluence, which are sometimes confusing in nuclear technologies: taking as a guide the medical meaning of a “dose” (the elementary ingestion of some drug), I proposed (up to now, without success) to name “elementary dose” the cascade (as defined by it’s size and density); the “dose rate” is the number of doses per unit time (and per unit quantity of matter) and the “integrated dose” is the integral of the latter. As we demonstrated and observed, the effect of a given irradiation depends on the three above parametersR5.

1994-... Configurational kinetics

As said above, driven alloys are such that two diffusion mechanisms are competing: a forced one, which is deduced from particle matter interaction, and the thermal one, which also operates in the absence of forcing. The reliability of modeling a kinetic pathway rests on the precision with which actual diffusion mechanisms are modeled. As we got involved in the field, most models were based on the kinetic Ising model, i.e. direct exchange diffusion mechanism and the same cohesive energy for the two components of the alloy, two features at variance of any metallurgical system: indeed, diffusion occurs because of vacancy jumps, and the alloy components have usually quite distinct cohesive energies, the latter scaling many of the vacancy properties (formation and migration energies). This was the driving force for revisiting the kinetic coefficient, which enters CahnHilliard’s diffusion equation. The expression we proposed, based on a broken bonds model, yields a unified description of configurational thermodynamics and kinetics, at the same level of sophistication104. Based on this model, we revisited many classical problems in solid-state kinetics, either using Kinetic Monte Carlo (KMC) simulations or various mean-field approximations:

  1. The realism of our KMC simulations has been assessed by comparing the precipitation of Ni3(Al,Cr) in a ternary model super alloy (NiAlCr) as observed by tomographic atom probe (TAP) and in our simulations191. In those days the improvement of the computing power, made it possible to run the real experiment and the virtual one on similar sample sizes. The quantitative and qualitative agreement between modeling and experiment was impressive. I improved the above study with D. Seidman, taking advantage of the recent explosion of the detection yield of Atom Probes. We could analyze a much greater number of precipitate nuclei, which revealed unexpected nuclei compositions and morphologies. The KMC simulations are based on first principle interatomic energies; the same parameters are used to compute the Onsager and diffusion matrices in the terminal solid solution. The origin of the unexpected features is demonstrated to be in the kinetic coupling among the fluxes of the alloy components, a coupling that is ignored by the classical models227, 232.

  2. More generic studies of kinetic pathways for the relaxation toward equilibrium were also

made, based on KMC simulations. We could identify the impact of the vacancy diffusion mechanism on various parameters such as the kinetic percolation limit, the Kolmogorov-Johnson-Mehl-Avrami exponent, or on qualitative features such as the uniform versus localized ordering process167, 173, 189, or the incubation time for precipitation193.

  1. Few problems with direct practical relevance could be addressed based on such a KMC technique: Cu precipitation in Fe160, formation of niobium carbides in low alloy steels, where the transient formation of a non-equilibrium iron carbide was predicted211.

The mean field approximation has been taken advantage of for revisiting basic problems of solidstate kinetics:

  1. Computing the Onsager matrix coefficients from the spectrum of defect (vacancy185 and

later self interstitial) jump frequencies; Studying the coupled relaxation of the order and composition fields (the classical model, which ignore that both fields relax because of the very same vacancy jumps, omit a coupling term)214, 157, 165; Expressing the interfacial transfer coefficient as a kinetic excess quantity129.

  1. Based on the same technique as the mean field model, we could study precipitation

complex alloy (Ag, In, Cd, Sn) undergoing transmutations, used as neutron absorber in PWR’s. Because the model used is based on a sound diffusion mechanism, the parameterization only required a small number of interdiffusion measurements175.

Studying precipitation phenomena, I focused on various aspects of the nucleation theories32, in particular on the free energy of a nucleus. Together with G. Jacucci (U. Trento, Italy) we used computer calorimetry to compute the latter in the Ising model (2 and 3 D), with a great level of accuracy: we could evaluate the correction to the capillarity approximation for small nuclei49, 57, 58. The free energies so computed can be used in cluster dynamics models for nucleation and growth. A direct assessment of the technique was done for the precipitation of AlZr, which was simulated using the KMC technique as described above, and using cluster dynamics parameterized as just described. The agreement is very good at least in the dilute case223. This research allowed to clarify some points of the classical nucleation theory224.

Miscellaneous

I did contribute to several studies which were underway in the laboratories I was the head of: metallurgy of quasi-crystals79, surface treatments by LASER heating70, interdiffusion induced amorphization83, 97, 115, kinetic pathways in epitaxial growth87, 88, 96,105, irradiation damage by swift ions63, 109…

The kinetics of morphological changes are fascinating, but difficult to phrase in general terms16: I addressed few questions such as the morphological stability of two phase super alloys with large precipitate volume fractions81, the rate of grain rotation across a grain boundary123, dewetting of a surface layer as a result of an interfacial reaction196, 202, 206, the incubation time for corrosion pitting82.

While the major part of my computer simulation work is based on Monte Carlo techniques, I devoted few years to using Molecular Dynamics to study atomistic aspects of crystalline plasticity:

dislocation pinning by small self interstitial clusters and the unpinning mechanisms in irradiated model Ni190, 199 and solute hardening in dilute Ni(Al) solutions219, 225. Both studies revealed features, which were not expected from continuum theories.

Managing research laboratories (1984-2002)

I had two very different experience of management: one at CNRS (1984-88), the other at CEASaclay (1989-2002).

At CNRS, the “Centre d'Études de Chimie Métallurgique” (Vitry sur Seine) was one of the earliest CNRS laboratories (50 years old), with about 60 scientists, 40 technical staff and 20 to 30 students. My main goal has been to stimulate a skill in modeling, in a community dominated by experimentalists, as well as forcing scientific communication among the teams.

At CEA, the Physical Metallurgy Laboratory (SRMP), which I was heading, underwent a deep renewal of people, because of the French retirement system. With 25 staff members, and 15 students, post-doc and visiting scientists, my main goal has been to keep and develop an expertise in the scientific basis for nuclear materials, at a time where such a field was temporarily outdated, and part of the team did work on problems like new routes of materials processing (mechanical alloying, electro deposition of High Tc superconductors...). Modeling from the atomic scale up has been the main achievement of that team; in particular, first-principle electronic structure computations were developed both for static and kinetic problems and provided the input parameters for atomic scale modeling. The cohabitation in the same small team of researches on very basic questions and researches on rather applied problems has been very stimulating, provided the communication among both sort of people could be maintained.

One of the major practical impacts of this expertise has been to introduce such techniques to the EDF research laboratory (EDF-Renardières, in the early 90’s).

Main scientific achievements

All of my work is motivated by developing basic science for materials technologies (nuclear and non nuclear).

1964-1977: Interfacial Diffusion

Grain-boundary (GB) diffusion was known to have a deleterious effect in the early nuclear fuel cladding (dispersion strengthened Mg) and, later, grain boundary electro migration was acknowledged to have a key role in the failure of micro-conductors in supercomputers. In this context, I measured two basic characteristics of grain boundary diffusion in a simple model metal, silver: the activation volume1 and the effective valence4, which measures the proportionality between the fluxes of atoms and of electrical charges. The measurements were performed on bycrystals, using radiotracer techniques, which implied very low activity measurements. The activation volume we measured pointed to a vacancy diffusion mechanism at the grain boundary (an unconventional idea in those days): this result got confirmed 20 years later in U. of Münster, in Germany. The effective valence we found was of the same sign as in the bulk, which ruled out some speculations in the literature on the possibility for hole conduction at the GB’s.

The GB diffusion models used at that time were very rough (a high diffusivity slab of finite thickness), while electron microscopy and field ion microscopy in metals were revealing undisturbed crystalline atomic packing up to the contact surface between the adjacent grains, in metals. For this reason, we proposed, together with Dr. P. Benoist (Wigner medal 1996), a lattice model for surface and GB diffusion, where the fast diffusion paths are confined to the contact surface between the two crystals9. We could thus specify the physical meaning of the parameters used in the classical models.

I later extended the formalism of GB diffusion to alloys17 and to phase boundaries10, two cases of practical relevance, where interfacial equilibrium conditions must be handled with care.

Other work included measuring the activation volume for Na diffusion in NaCl (at U of I Urbana, Pr. D. Lazarus), confirming a positive relaxation volume of the Schotky pair6, at variance with the best theoretical values of those days (the use of a linear approximation for the displacement to force ratio was at the origin of the error).

I also reformulated the rate of decay of capillarity waves, in the limit where adatom emission / absorption at surface steps is the rate controlling process, rather than surface diffusion from step to step (as postulated by Mullins in his famous work)21.

1969-1984: High temperature irradiation effects

In the late 60’s British scientists discovered irradiation induced swelling of stainless steel used as a cladding material in the Donrey fast reactor. The latter discovery triggered a worldwide interest. Swelling still raises problems in some core components of PWR’s. As is often the case in nuclear technologies, this swelling phenomenon challenged materials science and engineering, since no macroscopic theory can account for it: one must link the atomic scale, where nuclear collisions are well described, to the time evolution of the strain tensor, from which engineers can handle structural mechanics computations. This, I found very appealing.

My first contribution in this field together with Jean-Paul Poirier, dealt with the plastic deformation in metals under irradiation: based on simple defect balances we pointed, for the first time, to the possibility of a creep rate proportional to square of the shear stress2.

I then focused on more generic aspects of materials under high temperature irradiation, i.e. temperatures where the irradiation produced point defects can migrate distances large enough for a (quasi) stationary defect population to prevail in the solid. Such materials can be viewed as an open system sustained by external forcing (injection of defects) in some stationary state, the stability of which is not governed by thermodynamical potentials (an active field of research in the 70’s).

My first attempt along this line, dealt with the formation of void- (or other defect clusters) lattices13. According to this work, the latter appeared as a result of the spatial instability of the stationary uniform defect population, provided the defect-defect physical interaction is taken into account in the coupled reaction-diffusion equations, which govern time evolution of the vacancy and interstitial concentration fields. The model predicted that such a patterning would occur beyond some critical irradiation flux threshold, which depends on temperature, a prediction, which was confirmed by A. Barbu in his PhD thesis work.

This finding supported a suggestion by Adda et al. that depending on the irradiation flux and temperature, diffusion under irradiation might drive the material in opposite directions

(order/disorder, dissolution/precipitation, amorphization/crystallization…). A.Barbu22, 31 showed that such is indeed the case for irradiation induce precipitation in undersaturated solid solutions (Ni-Si).

My model also gave a general argument to account for irradiation-induced instability of undersaturated solid solutions28. Vacancy-interstitial mutual annealing introduces a weak coupling between the concentration fields of the solute and of the two types of defects: provided that the couplings between solute and defects fluxes is properly accounted for (“inverse Kirkendal effect”), the latter may destabilize the solid solution. Together with R. Cauvin26, 35, 36, 43, 54 we found evidence of such an effect in Al base solid solutions: the full spectrum of reaction to irradiation of many distinct solid solutions could be rationalized with the above argument, while constraint thermodynamics arguments failed to do so27. Potential consequences of the above mechanism on precipitate coarsening, or on the decomposition of INVAR alloys were explored together with K. Urban44 and C. Abromeit69, respectively.

The above formalism relied on the existence of stationary defect concentration fields, while the latter slowly evolve because of the microstructural evolution, which modifies the density of point defect sinks. Together with P. Valentin47, 51, 62, we modeled the coupled slow evolutions of various components of the microstructure, by eliminating the fast variables (defect concentration fields), which revealed some unexpected features, such as transient swelling, or a mechanism for the incubation of swelling, etc… One difficult point in modeling microstructures under irradiation deals with the evolution of the dislocation network. I addressed this problem very recently with D. Mordehai, paying special attention to the “coordinated climb” of neighboring dislocation segments231.

1984-1998 Driven alloys (for an overview, cf. ref. 166)

All the above models assumed that irradiation produces the point defects uniformly in space and time, while defects are produced in a correlated manner inside cascades, the size and density of which depends on the details of the slowing down of the irradiating particles. Moreover, cascades trigger local atomic mixing. From the theoretical viewpoint, cascades can be viewed as external noise imposed to the atomic configuration, with specific time and space correlation (at variance with thermal noise). A similar context prevails under sustained shear, such as during cyclic loading, materials processing by ball milling, etc… I suggested the analogy between the effects on phase stability, of irradiation and sustained shear in 198033.

Our first attempts failed to reveal any alteration of phase stability in Ni base binary solutions under high temperature cyclic loading, although an unexpected mechanism of bulk cavitation was found64. Several evidences of shear induced alteration of phase stability, such as precipitate dissolution in persistent slip bands or non-equilibrium segregations, were found by other groups, but were not rationalized with our ideas. Ball milling, on the other hand turned out to be more successful: we could define a “milling intensity” and demonstrate on model alloys (mainly FeAl and NixZry compounds) that under milling, the alloy achieves a state (ordered or disordered, crystalline or amorphous), which depends on the milling conditions (intensity and temperature). The analogy with irradiation effects was established137, 156. Advantage could be taken of this analogy in several studies of practical impact: optimizing the processing route of dispersed oxide compounds for electrical contact142 (among others), understanding the wear process of swift trains wheels217, and more recently optimizing drug processing by milling (M. Descamp, AIP Conference Proceedings, Volume 982, 2008,

53-61).

Developing the theory of driven alloys spread on a long period of time. The effect of “ballistic mixing”, i.e. the atomic mixing forced by nuclear collisions or dislocation glide during shearing, was first treated by simply superimposing forced atomic jumps to the thermally activated ones in a Cahn Hilliard type diffusion equation. The result was that the evolution of the solute concentration field is no more governed by the Gibbs free energy functional, but by a Lyapunov functional; the latter writes as the Gibbs free energy evaluated at an “effective temperature”, which depends on the ratio of the forced to the thermal atomic jump frequencies56. This idea yields qualitatively and sometimes quantitatively corrects results93.

We addressed the problem with increasing levels of sophistication:

  1. The state of the compound is defined by a uniform order parameter, the value of which is

governed by a the deterministic equation: single or multiple stationary states are found, depending on the forcing intensity and temperature, the local stability of which can be assessed74,121.

  1. The state of the compound is defined by a field of order parameter, the evolution of which

is governed by time dependant Gingsburg Landau equation. Special care had to be devoted to the expression of the kinetic coefficient under purely thermal conditions. I proposed a mean field approximation, which treats thermodynamics and kinetics at the same level of sophistication104. Based on this model, several problems could be addressed: coarsening under irradiation, kinetic pathways for precipitate dissolution, revealing the key role, on top of the reduce temperature, of the forcing intensity132, 143, 145. A practical application of the above technique dealt with irradiation induced interfacial segregations, a key issue in stress corrosion cracking of core components153, 184.

  1. The above technique could incorporate “inverse Kirkendal effect” on top of ballistic

mixing, yielding a unified treatment of both effects166.

  1. Keeping the homogeneous description, we addressed the stochastic aspect of the problem,

based on a Fokker Planck or Kubo equation85, 86, 90, 92, 98, 113. From these treatments, we could propose phase diagrams of dynamical-equilibrium under irradiation for model compounds (FeAl and Ni4Mo), several predictions of which have been later confirmed by experiment. E.g. the order disorder transition in FeAl, which is of second order shifts to first order under appropriate irradiation conditions147, the extension of the stability domain of ordered structures in Ni4Mo, varies with the size of the cascade, keeping the irradiation flux the same (experiments done in Argonne by Bellon et al. and in HMI by Banerjee et al.). Kinetic Monte Carlo simulations enriched the theoretical treatment150.

One of the applications of the above ideas about dynamical equilibria and microstructural evolution under irradiation dealt with the surprisingly good irradiation resistance of brazing of common use in PWR’s: the brittle Ni phosphides either amorphize or develop a dislocation network which makes them more ductile126!

On a more general level, the above results might be used to clarify the notions of dose, dose rate, flux, fluence, which are sometimes confusing in nuclear technologies: taking as a guide the medical meaning of a “dose” (the elementary ingestion of some drug), I proposed (up to now, without success) to name “elementary dose” the cascade (as defined by it’s size and density); the “dose rate” is the number of doses per unit time (and per unit quantity of matter) and the “integrated dose” is the integral of the latter. As we demonstrated and observed, the effect of a given irradiation depends on the three above parametersR5.

1994-... Configurational kinetics

As said above, driven alloys are such that two diffusion mechanisms are competing: a forced one, which is deduced from particle matter interaction, and the thermal one, which also operates in the absence of forcing. The reliability of modeling a kinetic pathway rests on the precision with which actual diffusion mechanisms are modeled. As we got involved in the field, most models were based on the kinetic Ising model, i.e. direct exchange diffusion mechanism and the same cohesive energy for the two components of the alloy, two features at variance of any metallurgical system: indeed, diffusion occurs because of vacancy jumps, and the alloy components have usually quite distinct cohesive energies, the latter scaling many of the vacancy properties (formation and migration energies). This was the driving force for revisiting the kinetic coefficient, which enters CahnHilliard’s diffusion equation. The expression we proposed, based on a broken bonds model, yields a unified description of configurational thermodynamics and kinetics, at the same level of sophistication104. Based on this model, we revisited many classical problems in solid-state kinetics, either using Kinetic Monte Carlo (KMC) simulations or various mean-field approximations:

  1. The realism of our KMC simulations has been assessed by comparing the precipitation of Ni3(Al,Cr) in a ternary model super alloy (NiAlCr) as observed by tomographic atom probe (TAP) and in our simulations191. In those days the improvement of the computing power, made it possible to run the real experiment and the virtual one on similar sample sizes. The quantitative and qualitative agreement between modeling and experiment was impressive. I improved the above study with D. Seidman, taking advantage of the recent explosion of the detection yield of Atom Probes. We could analyze a much greater number of precipitate nuclei, which revealed unexpected nuclei compositions and morphologies. The KMC simulations are based on first principle interatomic energies; the same parameters are used to compute the Onsager and diffusion matrices in the terminal solid solution. The origin of the unexpected features is demonstrated to be in the kinetic coupling among the fluxes of the alloy components, a coupling that is ignored by the classical models227, 232.

  2. More generic studies of kinetic pathways for the relaxation toward equilibrium were also

made, based on KMC simulations. We could identify the impact of the vacancy diffusion mechanism on various parameters such as the kinetic percolation limit, the Kolmogorov-Johnson-Mehl-Avrami exponent, or on qualitative features such as the uniform versus localized ordering process167, 173, 189, or the incubation time for precipitation193.

  1. Few problems with direct practical relevance could be addressed based on such a KMC technique: Cu precipitation in Fe160, formation of niobium carbides in low alloy steels, where the transient formation of a non-equilibrium iron carbide was predicted211.

The mean field approximation has been taken advantage of for revisiting basic problems of solidstate kinetics:

  1. Computing the Onsager matrix coefficients from the spectrum of defect (vacancy185 and

later self interstitial) jump frequencies; Studying the coupled relaxation of the order and composition fields (the classical model, which ignore that both fields relax because of the very same vacancy jumps, omit a coupling term)214, 157, 165; Expressing the interfacial transfer coefficient as a kinetic excess quantity129.

  1. Based on the same technique as the mean field model, we could study precipitation

complex alloy (Ag, In, Cd, Sn) undergoing transmutations, used as neutron absorber in PWR’s. Because the model used is based on a sound diffusion mechanism, the parameterization only required a small number of interdiffusion measurements175.

Studying precipitation phenomena, I focused on various aspects of the nucleation theories32, in particular on the free energy of a nucleus. Together with G. Jacucci (U. Trento, Italy) we used computer calorimetry to compute the latter in the Ising model (2 and 3 D), with a great level of accuracy: we could evaluate the correction to the capillarity approximation for small nuclei49, 57, 58. The free energies so computed can be used in cluster dynamics models for nucleation and growth. A direct assessment of the technique was done for the precipitation of AlZr, which was simulated using the KMC technique as described above, and using cluster dynamics parameterized as just described. The agreement is very good at least in the dilute case223. This research allowed to clarify some points of the classical nucleation theory224.

Miscellaneous

I did contribute to several studies which were underway in the laboratories I was the head of: metallurgy of quasi-crystals79, surface treatments by LASER heating70, interdiffusion induced amorphization83, 97, 115, kinetic pathways in epitaxial growth87, 88, 96,105, irradiation damage by swift ions63, 109…

The kinetics of morphological changes are fascinating, but difficult to phrase in general terms16: I addressed few questions such as the morphological stability of two phase super alloys with large precipitate volume fractions81, the rate of grain rotation across a grain boundary123, dewetting of a surface layer as a result of an interfacial reaction196, 202, 206, the incubation time for corrosion pitting82.

While the major part of my computer simulation work is based on Monte Carlo techniques, I devoted few years to using Molecular Dynamics to study atomistic aspects of crystalline plasticity:

dislocation pinning by small self interstitial clusters and the unpinning mechanisms in irradiated model Ni190, 199 and solute hardening in dilute Ni(Al) solutions219, 225. Both studies revealed features, which were not expected from continuum theories.

Managing research laboratories (1984-2002)

I had two very different experience of management: one at CNRS (1984-88), the other at CEASaclay (1989-2002).

At CNRS, the “Centre d'Études de Chimie Métallurgique” (Vitry sur Seine) was one of the earliest CNRS laboratories (50 years old), with about 60 scientists, 40 technical staff and 20 to 30 students. My main goal has been to stimulate a skill in modeling, in a community dominated by experimentalists, as well as forcing scientific communication among the teams.

At CEA, the Physical Metallurgy Laboratory (SRMP), which I was heading, underwent a deep renewal of people, because of the French retirement system. With 25 staff members, and 15 students, post-doc and visiting scientists, my main goal has been to keep and develop an expertise in the scientific basis for nuclear materials, at a time where such a field was temporarily outdated, and part of the team did work on problems like new routes of materials processing (mechanical alloying, electro deposition of High Tc superconductors...). Modeling from the atomic scale up has been the main achievement of that team; in particular, first-principle electronic structure computations were developed both for static and kinetic problems and provided the input parameters for atomic scale modeling. The cohabitation in the same small team of researches on very basic questions and researches on rather applied problems has been very stimulating, provided the communication among both sort of people could be maintained.

One of the major practical impacts of this expertise has been to introduce such techniques to the EDF research laboratory (EDF-Renardières, in the early 90’s).

Main scientific achievements

All of my work is motivated by developing basic science for materials technologies (nuclear and non nuclear).

1964-1977: Interfacial Diffusion

Grain-boundary (GB) diffusion was known to have a deleterious effect in the early nuclear fuel cladding (dispersion strengthened Mg) and, later, grain boundary electro migration was acknowledged to have a key role in the failure of micro-conductors in supercomputers. In this context, I measured two basic characteristics of grain boundary diffusion in a simple model metal, silver: the activation volume1 and the effective valence4, which measures the proportionality between the fluxes of atoms and of electrical charges. The measurements were performed on bycrystals, using radiotracer techniques, which implied very low activity measurements. The activation volume we measured pointed to a vacancy diffusion mechanism at the grain boundary (an unconventional idea in those days): this result got confirmed 20 years later in U. of Münster, in Germany. The effective valence we found was of the same sign as in the bulk, which ruled out some speculations in the literature on the possibility for hole conduction at the GB’s.

The GB diffusion models used at that time were very rough (a high diffusivity slab of finite thickness), while electron microscopy and field ion microscopy in metals were revealing undisturbed crystalline atomic packing up to the contact surface between the adjacent grains, in metals. For this reason, we proposed, together with Dr. P. Benoist (Wigner medal 1996), a lattice model for surface and GB diffusion, where the fast diffusion paths are confined to the contact surface between the two crystals9. We could thus specify the physical meaning of the parameters used in the classical models.

I later extended the formalism of GB diffusion to alloys17 and to phase boundaries10, two cases of practical relevance, where interfacial equilibrium conditions must be handled with care.

Other work included measuring the activation volume for Na diffusion in NaCl (at U of I Urbana, Pr. D. Lazarus), confirming a positive relaxation volume of the Schotky pair6, at variance with the best theoretical values of those days (the use of a linear approximation for the displacement to force ratio was at the origin of the error).

I also reformulated the rate of decay of capillarity waves, in the limit where adatom emission / absorption at surface steps is the rate controlling process, rather than surface diffusion from step to step (as postulated by Mullins in his famous work)21.

1969-1984: High temperature irradiation effects

In the late 60’s British scientists discovered irradiation induced swelling of stainless steel used as a cladding material in the Donrey fast reactor. The latter discovery triggered a worldwide interest. Swelling still raises problems in some core components of PWR’s. As is often the case in nuclear technologies, this swelling phenomenon challenged materials science and engineering, since no macroscopic theory can account for it: one must link the atomic scale, where nuclear collisions are well described, to the time evolution of the strain tensor, from which engineers can handle structural mechanics computations. This, I found very appealing.

My first contribution in this field together with Jean-Paul Poirier, dealt with the plastic deformation in metals under irradiation: based on simple defect balances we pointed, for the first time, to the possibility of a creep rate proportional to square of the shear stress2.

I then focused on more generic aspects of materials under high temperature irradiation, i.e. temperatures where the irradiation produced point defects can migrate distances large enough for a (quasi) stationary defect population to prevail in the solid. Such materials can be viewed as an open system sustained by external forcing (injection of defects) in some stationary state, the stability of which is not governed by thermodynamical potentials (an active field of research in the 70’s).

My first attempt along this line, dealt with the formation of void- (or other defect clusters) lattices13. According to this work, the latter appeared as a result of the spatial instability of the stationary uniform defect population, provided the defect-defect physical interaction is taken into account in the coupled reaction-diffusion equations, which govern time evolution of the vacancy and interstitial concentration fields. The model predicted that such a patterning would occur beyond some critical irradiation flux threshold, which depends on temperature, a prediction, which was confirmed by A. Barbu in his PhD thesis work.

This finding supported a suggestion by Adda et al. that depending on the irradiation flux and temperature, diffusion under irradiation might drive the material in opposite directions

(order/disorder, dissolution/precipitation, amorphization/crystallization…). A.Barbu22, 31 showed that such is indeed the case for irradiation induce precipitation in undersaturated solid solutions (Ni-Si).

My model also gave a general argument to account for irradiation-induced instability of undersaturated solid solutions28. Vacancy-interstitial mutual annealing introduces a weak coupling between the concentration fields of the solute and of the two types of defects: provided that the couplings between solute and defects fluxes is properly accounted for (“inverse Kirkendal effect”), the latter may destabilize the solid solution. Together with R. Cauvin26, 35, 36, 43, 54 we found evidence of such an effect in Al base solid solutions: the full spectrum of reaction to irradiation of many distinct solid solutions could be rationalized with the above argument, while constraint thermodynamics arguments failed to do so27. Potential consequences of the above mechanism on precipitate coarsening, or on the decomposition of INVAR alloys were explored together with K. Urban44 and C. Abromeit69, respectively.

The above formalism relied on the existence of stationary defect concentration fields, while the latter slowly evolve because of the microstructural evolution, which modifies the density of point defect sinks. Together with P. Valentin47, 51, 62, we modeled the coupled slow evolutions of various components of the microstructure, by eliminating the fast variables (defect concentration fields), which revealed some unexpected features, such as transient swelling, or a mechanism for the incubation of swelling, etc… One difficult point in modeling microstructures under irradiation deals with the evolution of the dislocation network. I addressed this problem very recently with D. Mordehai, paying special attention to the “coordinated climb” of neighboring dislocation segments231.

1984-1998 Driven alloys (for an overview, cf. ref. 166)

All the above models assumed that irradiation produces the point defects uniformly in space and time, while defects are produced in a correlated manner inside cascades, the size and density of which depends on the details of the slowing down of the irradiating particles. Moreover, cascades trigger local atomic mixing. From the theoretical viewpoint, cascades can be viewed as external noise imposed to the atomic configuration, with specific time and space correlation (at variance with thermal noise). A similar context prevails under sustained shear, such as during cyclic loading, materials processing by ball milling, etc… I suggested the analogy between the effects on phase stability, of irradiation and sustained shear in 198033.

Our first attempts failed to reveal any alteration of phase stability in Ni base binary solutions under high temperature cyclic loading, although an unexpected mechanism of bulk cavitation was found64. Several evidences of shear induced alteration of phase stability, such as precipitate dissolution in persistent slip bands or non-equilibrium segregations, were found by other groups, but were not rationalized with our ideas. Ball milling, on the other hand turned out to be more successful: we could define a “milling intensity” and demonstrate on model alloys (mainly FeAl and NixZry compounds) that under milling, the alloy achieves a state (ordered or disordered, crystalline or amorphous), which depends on the milling conditions (intensity and temperature). The analogy with irradiation effects was established137, 156. Advantage could be taken of this analogy in several studies of practical impact: optimizing the processing route of dispersed oxide compounds for electrical contact142 (among others), understanding the wear process of swift trains wheels217, and more recently optimizing drug processing by milling (M. Descamp, AIP Conference Proceedings, Volume 982, 2008,

53-61).

Developing the theory of driven alloys spread on a long period of time. The effect of “ballistic mixing”, i.e. the atomic mixing forced by nuclear collisions or dislocation glide during shearing, was first treated by simply superimposing forced atomic jumps to the thermally activated ones in a Cahn Hilliard type diffusion equation. The result was that the evolution of the solute concentration field is no more governed by the Gibbs free energy functional, but by a Lyapunov functional; the latter writes as the Gibbs free energy evaluated at an “effective temperature”, which depends on the ratio of the forced to the thermal atomic jump frequencies56. This idea yields qualitatively and sometimes quantitatively corrects results93.

We addressed the problem with increasing levels of sophistication:

  1. The state of the compound is defined by a uniform order parameter, the value of which is

governed by a the deterministic equation: single or multiple stationary states are found, depending on the forcing intensity and temperature, the local stability of which can be assessed74,121.

  1. The state of the compound is defined by a field of order parameter, the evolution of which

is governed by time dependant Gingsburg Landau equation. Special care had to be devoted to the expression of the kinetic coefficient under purely thermal conditions. I proposed a mean field approximation, which treats thermodynamics and kinetics at the same level of sophistication104. Based on this model, several problems could be addressed: coarsening under irradiation, kinetic pathways for precipitate dissolution, revealing the key role, on top of the reduce temperature, of the forcing intensity132, 143, 145. A practical application of the above technique dealt with irradiation induced interfacial segregations, a key issue in stress corrosion cracking of core components153, 184.

  1. The above technique could incorporate “inverse Kirkendal effect” on top of ballistic

mixing, yielding a unified treatment of both effects166.

  1. Keeping the homogeneous description, we addressed the stochastic aspect of the problem,

based on a Fokker Planck or Kubo equation85, 86, 90, 92, 98, 113. From these treatments, we could propose phase diagrams of dynamical-equilibrium under irradiation for model compounds (FeAl and Ni4Mo), several predictions of which have been later confirmed by experiment. E.g. the order disorder transition in FeAl, which is of second order shifts to first order under appropriate irradiation conditions147, the extension of the stability domain of ordered structures in Ni4Mo, varies with the size of the cascade, keeping the irradiation flux the same (experiments done in Argonne by Bellon et al. and in HMI by Banerjee et al.). Kinetic Monte Carlo simulations enriched the theoretical treatment150.

One of the applications of the above ideas about dynamical equilibria and microstructural evolution under irradiation dealt with the surprisingly good irradiation resistance of brazing of common use in PWR’s: the brittle Ni phosphides either amorphize or develop a dislocation network which makes them more ductile126!

On a more general level, the above results might be used to clarify the notions of dose, dose rate, flux, fluence, which are sometimes confusing in nuclear technologies: taking as a guide the medical meaning of a “dose” (the elementary ingestion of some drug), I proposed (up to now, without success) to name “elementary dose” the cascade (as defined by it’s size and density); the “dose rate” is the number of doses per unit time (and per unit quantity of matter) and the “integrated dose” is the integral of the latter. As we demonstrated and observed, the effect of a given irradiation depends on the three above parametersR5.

1994-... Configurational kinetics

As said above, driven alloys are such that two diffusion mechanisms are competing: a forced one, which is deduced from particle matter interaction, and the thermal one, which also operates in the absence of forcing. The reliability of modeling a kinetic pathway rests on the precision with which actual diffusion mechanisms are modeled. As we got involved in the field, most models were based on the kinetic Ising model, i.e. direct exchange diffusion mechanism and the same cohesive energy for the two components of the alloy, two features at variance of any metallurgical system: indeed, diffusion occurs because of vacancy jumps, and the alloy components have usually quite distinct cohesive energies, the latter scaling many of the vacancy properties (formation and migration energies). This was the driving force for revisiting the kinetic coefficient, which enters CahnHilliard’s diffusion equation. The expression we proposed, based on a broken bonds model, yields a unified description of configurational thermodynamics and kinetics, at the same level of sophistication104. Based on this model, we revisited many classical problems in solid-state kinetics, either using Kinetic Monte Carlo (KMC) simulations or various mean-field approximations:

  1. The realism of our KMC simulations has been assessed by comparing the precipitation of Ni3(Al,Cr) in a ternary model super alloy (NiAlCr) as observed by tomographic atom probe (TAP) and in our simulations191. In those days the improvement of the computing power, made it possible to run the real experiment and the virtual one on similar sample sizes. The quantitative and qualitative agreement between modeling and experiment was impressive. I improved the above study with D. Seidman, taking advantage of the recent explosion of the detection yield of Atom Probes. We could analyze a much greater number of precipitate nuclei, which revealed unexpected nuclei compositions and morphologies. The KMC simulations are based on first principle interatomic energies; the same parameters are used to compute the Onsager and diffusion matrices in the terminal solid solution. The origin of the unexpected features is demonstrated to be in the kinetic coupling among the fluxes of the alloy components, a coupling that is ignored by the classical models227, 232.

  2. More generic studies of kinetic pathways for the relaxation toward equilibrium were also

made, based on KMC simulations. We could identify the impact of the vacancy diffusion mechanism on various parameters such as the kinetic percolation limit, the Kolmogorov-Johnson-Mehl-Avrami exponent, or on qualitative features such as the uniform versus localized ordering process167, 173, 189, or the incubation time for precipitation193.

  1. Few problems with direct practical relevance could be addressed based on such a KMC technique: Cu precipitation in Fe160, formation of niobium carbides in low alloy steels, where the transient formation of a non-equilibrium iron carbide was predicted211.

The mean field approximation has been taken advantage of for revisiting basic problems of solidstate kinetics:

  1. Computing the Onsager matrix coefficients from the spectrum of defect (vacancy185 and

later self interstitial) jump frequencies; Studying the coupled relaxation of the order and composition fields (the classical model, which ignore that both fields relax because of the very same vacancy jumps, omit a coupling term)214, 157, 165; Expressing the interfacial transfer coefficient as a kinetic excess quantity129.

  1. Based on the same technique as the mean field model, we could study precipitation

complex alloy (Ag, In, Cd, Sn) undergoing transmutations, used as neutron absorber in PWR’s. Because the model used is based on a sound diffusion mechanism, the parameterization only required a small number of interdiffusion measurements175.

Studying precipitation phenomena, I focused on various aspects of the nucleation theories32, in particular on the free energy of a nucleus. Together with G. Jacucci (U. Trento, Italy) we used computer calorimetry to compute the latter in the Ising model (2 and 3 D), with a great level of accuracy: we could evaluate the correction to the capillarity approximation for small nuclei49, 57, 58. The free energies so computed can be used in cluster dynamics models for nucleation and growth. A direct assessment of the technique was done for the precipitation of AlZr, which was simulated using the KMC technique as described above, and using cluster dynamics parameterized as just described. The agreement is very good at least in the dilute case223. This research allowed to clarify some points of the classical nucleation theory224.

Miscellaneous

I did contribute to several studies which were underway in the laboratories I was the head of: metallurgy of quasi-crystals79, surface treatments by LASER heating70, interdiffusion induced amorphization83, 97, 115, kinetic pathways in epitaxial growth87, 88, 96,105, irradiation damage by swift ions63, 109…

The kinetics of morphological changes are fascinating, but difficult to phrase in general terms16: I addressed few questions such as the morphological stability of two phase super alloys with large precipitate volume fractions81, the rate of grain rotation across a grain boundary123, dewetting of a surface layer as a result of an interfacial reaction196, 202, 206, the incubation time for corrosion pitting82.

While the major part of my computer simulation work is based on Monte Carlo techniques, I devoted few years to using Molecular Dynamics to study atomistic aspects of crystalline plasticity:

dislocation pinning by small self interstitial clusters and the unpinning mechanisms in irradiated model Ni190, 199 and solute hardening in dilute Ni(Al) solutions219, 225. Both studies revealed features, which were not expected from continuum theories.

Managing research laboratories (1984-2002)

I had two very different experience of management: one at CNRS (1984-88), the other at CEASaclay (1989-2002).

At CNRS, the “Centre d'Études de Chimie Métallurgique” (Vitry sur Seine) was one of the earliest CNRS laboratories (50 years old), with about 60 scientists, 40 technical staff and 20 to 30 students. My main goal has been to stimulate a skill in modeling, in a community dominated by experimentalists, as well as forcing scientific communication among the teams.

At CEA, the Physical Metallurgy Laboratory (SRMP), which I was heading, underwent a deep renewal of people, because of the French retirement system. With 25 staff members, and 15 students, post-doc and visiting scientists, my main goal has been to keep and develop an expertise in the scientific basis for nuclear materials, at a time where such a field was temporarily outdated, and part of the team did work on problems like new routes of materials processing (mechanical alloying, electro deposition of High Tc superconductors...). Modeling from the atomic scale up has been the main achievement of that team; in particular, first-principle electronic structure computations were developed both for static and kinetic problems and provided the input parameters for atomic scale modeling. The cohabitation in the same small team of researches on very basic questions and researches on rather applied problems has been very stimulating, provided the communication among both sort of people could be maintained.

One of the major practical impacts of this expertise has been to introduce such techniques to the EDF research laboratory (EDF-Renardières, in the early 90’s).
