英文摘要
The configurational entropy formula of the Cluster Variation Method in the octahedron approximation for the bcc structure has been derived, and the CVM has been applied to the analysis on the order-disorder transition in the V-H system. It has been confirmed that both the third and fourth nearest neighbor pair interactions, v_ 3 and v_ 4, stabilize the ordered phase and strongly affect the transition. The narrow width of the two phase region show that the order-disorder transition is the first order, but is extremely close to the second order.
