Effects of Continuous Atomic Displacement on the Phase Stability of Metallic Alloys
The cluster variation method (CVM) has been introduced by Kikuchi , and successfully applied to various problems of solid state physics and materials science. For instance, it has been used extensively to investigate temperature-composition phase diagrams of alloys. In the CVM calculations, however, the entropy expression was formulated for permutations of atoms among rigid lattice points. This type of approach will be referred to as the conventional CVM [1,2] in the present paper.
