A new technique of electron Spectroscopy is described in which a standard electron spectrometer is used to compare the electron energy to be measured with the energies of electrons from a field-emitter reference source. Since the reference electrons are emitted at the Fermi level of the emitter tip, their total energy can be accurately measured with a high precision digital voltmeter. The measurements are automatically referenced to the absolute scale of energies and the need for calibration standards is eliminated. The application of the technique to X-ray photoelectron Spectroscopy (XPS) is described. Detailed analysis shows that the uncertainty in the field-emitter referenced XPS measurements is ± 0.06 electron volts. |

The microstructural evolution during hot extrusion and post heat treatment was investigated for two kind of Al–Zn–Mg–Cu–(Sc) alloy and AA7075. The microstructure of as-extruded bar is mainly comprised of recovered structure for all alloys, however, different restoration processes are observed during post heat treatment. For AA7075 and S1, which contains 0.1% Sc with relatively higher Zn and Cu content than S2, recovery still proceeds during the heat treatment, while the recrystallization becomes main restoration process during the heat treatment for S2.
The differences in abnormal grain growth and hardening behavior between S1, AA7075 and S2 during the heat treatment are discussed in connection with the restoration processes and resultant microstructures. |

Grain growth in nanocrystalline (nc) Al with a grain size of 26 nm produced by cryogenic mechanical milling was studied through x-ray diffraction, transmission electron microscopy, and differential scanning calorimetry. Grain growth kinetics resembled those of ball-milled nc Fe. For homologous temperatures (T/TM) of 0.61-0.83, the time exponent n from D1/n - D01/n = kt was 0.04-0.28, tending toward 0.5 as T/TM increased. Two grain-growth regimes were distinguished: below T/TM = 0.78 growth ceased at an approximate grain size of 50 nm while at higher temperatures, grain growth proceeded steadily to the submicrometer range. Grain growth over the range of temperatures studied cannot be explained in terms of a single thermally activated rate process. The observed high grain size stability was attributed primarily to impurity pinning drag associated with the grain growth process. |

Cast nickel-base superalloys possess the required mechanical properties (creep resistance and stress rupture life) at elevated temperatures that make them suitable for turbine blades in aero-engines. The origin of these properties lies in the presence of a simple two phase [gamma]-[gamma]' microstructure (with cuboidal [gamma]' particles dispersed in a [gamma] matrix), in spite of the presence of several alloying elements. The cuboidal nature of the [gamma]' particles arises from an optimal misfit between the two phases, which is a function of the composition of [gamma] and [gamma]' phases. In addition, several microstructural issues arising out of the partitioning of the alloying elements influences directly the deformation mechanisms in the [gamma] and [gamma]', and therefore the mechanical properties of the alloy. In this article, we discuss how some of these microstructural issues have been investigated in DMS4, a cast single crystal superalloy, experimentally using TEM and 3DAP techniques. |
