Alloy design based on predictions of atomic configuration
Atomic configurations such as long range ordering and short range ordering
not only play a significant role on relative phase equilibrium but also
affect physical properties of alloys. For establishing materials design
technologies based on predictions of atomic configuration, the cluster
variation method and the central atoms model have been applied to thermodynamic
analyses on atomic configurations in the intermetallic compounds and solid
solution alloys, respectively. For nanocrystalline and amorphous alloys,
microstructural analyses have been performed by small-angle X-ray experiments
and the molecular dynamics simulation to make clear the formation process
of these microstructures on the atomic level.
