利用CALPHAD方法,采用亚正规溶体模型、亚点阵模型以及理想气体模型来描述RE-X(Ag,Bi,Cr,Mn,Mo,V,Zn)中二元系各相的Gibbs自由能,并结合相平衡及热力学性质的实验结果,对Ag-RE(RE:Sc,Y Nd,Sm,Gd,.Tb,Ho,Er)、Bi-RE(RE:Nd,Tm,Er,Ho,Pr,Gd)、Cr-RE(RE:Ce,Nd,Sm,Lu)、Mn-RE(RE:Pr,Nd,Sm,Eu,Tb,Dy,Ho,Er,Tm,Yb,Lu)、Mo-RE(RE:Se,Y,La,Ce,Pr,Nd,Sm,Eu,Tb,Oy,Ho,Er,Tm,Yb,Lu)、V-RE(RE:La,Ce,Pr,Nd,Ho,Lu)和Zn-RE(RE:Y,Ce,Pr,Sd,Sm)各二元系相图进行热力学优化与计算.计算结果与实验数据取得很好的一致性,并结合其他相关稀土二元系相图热力学计算,初步建立部分稀土二元合金相图的热力学数据库.该热力学数据库可以提供相平衡及热力学性质等多种信息,为外推计算稀土多组元体系的相平衡提供理论基础,并为高性能稀土合金材料的设计及制备提供重要的理论指导.
