Partitioning of Co during crystallisation of FeCoNbB(Cu) amorphous alloys Journal Article 2003 Materials Science and Engineering A Mater. Sci. Eng. A 353 1-2 158-163 Amorphous; Soft magnetic; Atom probe; Nanocrystallisation; Microstructure Partitioning behaviour of alloying elements during the primary crystallisation of both Fe18Co60Nb6B16 and Fe39Co39Nb6B15Cu1 alloys has been studied using three-dimensional atom probe (3DAP). Cu rich clusters were found in the Cu-containing alloy, and they provided nucleation sites for the primary α-Fe(Co) particles. In the Cu clusters, concentration of both Fe and Co was greatly decreased. In both Cu-containing and Cu-free alloys Nb and B were depleted in the α-Fe(Co) particles and enriched in the remaining amorphous phase. However, Co concentration in the α-Fe(Co) was the same as the remaining amorphous phase. Based on the 3DAP analysis, the phase volume fraction has been estimated. no NU @ karnesky @ 818

Zhang, Tong-Yi; Ren, Hang Solute concentrations and strains in nanograined materials Journal Article 2013 Acta Materialia 61 2 477-493 Nanograined materials; Grain boundary segregation; Stresses; Solute concentrations; Coupling between stress and concentration Taking advantage of both the Gibbs and McLean adsorption isotherms, we develop a Gibbs-approach-based adsorption isotherm for grain boundary (GB) segregation in nanograined (ng) polycrystals. An excess GB thickness is introduced to describe the excess of GB atomic volume in comparison with the atomic volume in lattice. The GB bulk modulus is determined with the excess GB thickness and a universal function. The newly developed adsorption isotherm is able to analyze simultaneously stresses, concentrations and their coupling behaviors in grains and GBs. Numerical calculations and plots are conducted to illustrate the theoretical analysis. The results show that the apparent solute concentration could be greatly enhanced in ng materials, due to a large grain boundary volume fraction and a considerable increase in the lattice concentration that is, in turn, boosted by the concentration-induced stresses. 1359-6454 no NU @ karnesky @ 11418

Zhang, Guo Fan; Sauvage, Xavier; Wang, Jing Tao; Gao, Nong; Langdon, Terence G. Decomposition of Nanostructured Martensite in Cu-Al Alloys Processed by High-Pressure Torsion Journal Article 2010 Materials Science Forum 667-669 469-474 The phase decomposition was investigated in Cu-Al alloys processed to a nanostructure condition by High Pressure Torsion (HPT). The microstructures are characterized by optical microscopy (OM), X-ray diffraction (XRD) and Atom Probe Tomography (APT). The results show that the → (1 + decomposition reaction begins in the early stage of annealing and it is much faster than in the coarse-grained state although there are similar phases after annealing. 1662-9752 no NU @ karnesky @ zhang_decomposition_2010 11324
