Abstract: Comprehensively considering energy, volume and electronic structure of alloys, the ninth equation was determined as the interaction function of Nb−Mo alloys system in BCC structure on the basis of idea of systematic science of alloys, experimental lattice constants and heats of formation of disordered Nb(1−x)Mox alloys. The structural parameters and properties of Nb and Mo characteristic atoms sequences and corresponding characteristic crystals sequences were determined in Nb−Mo alloys system. The electronic structure and physical properties of disordered Nb(1−x)Mox alloys system were calculated according to concentration of characteristic atoms of disordered alloys. The change trend of physical properties is the same as that of electronic structure.
Key words: Nb−Mo alloys system; characteristic atom sequences; disordered alloys; properties
