摘要
Phase equilibria at elevated temperatures are important to extensive research on FeAlintermetallic compound. The cluster variation method (CVM) and the naturaliteration method (NIM) proposed by Kikuchi are effective in calculating equilibria andthermodynamic properties of alloys.By using these methods. Wu and Zheng et al. cal-culated the phase diagrame of Fe-Mn. Ag-Au and Au-Cu binary alloys and obtained
