nearly thirty years of efforts, XIE et al [1-12] had established the framework of systematic science of alloys on the basis of energy band theory, valence bond theory and statistical thermodynamics..., Ti-Al alloys with coexistence of FCC and HCP structures [9-12]. However, there is little research on alloys in BCC structure by the theory. The purpose of the present work is to choose Nb-Mo alloys......
