摘要
Based on the empirical electron theory of solids and molecules developed by Yu Rui-huang, a theoretical model for calculating the free energies of bcc and fcc binary alloys ispresented. The equilibrium-phase diagram of the Fe-Mn system in a high-temperature rangeis calculated using the cluster variation method and Yu’s bond energy formulae. The calcu-lated results are found to be in good agreement with experiments.
