Cluster Variation Study of Coherent Ordering in FCC and BCC Solid Solutions

摘要

The primary objective of this investigation was the derivation of binary phase diagrams by means of a statistical mechanical model called the Cluster Variation Method. In particular, phase equilibrium as a function of the ratio between the values of second and first neighbor effective pair interactions, the ratio being the only physical input to the computer codes. The resulting phase diagrams are important for the purpose of analyzing experimentally determined alloy phase diagrams.
