摘要
利用气液平衡实验方法和三元系液态合金元组间相互作用系数的计算模型，测定和计算了Ｆｅ－Ｂｉ－ｊ三元溶液体系在１８７３Ｋ时第三组合组元Ｃｒ，Ｃｕ，Ｃ，Ａｌ和Ｓｉ对Ｂｉ的活度相互作用系数以及ｌｎγ＾０值。实验值与模型计算值符合良好。
The activity interaction coefficient and lnγ of the Fe-Bi-j(j =Cr ,Cu ,C ,Al ,Si) ternary liquid solutions were determined by means of vapor pressure method at 1873K and a new model is proposed by using of free volume theory,Miedema's semi-empirical formular and Toop s geometrical model. The results calculated from the model are good in agreement with the experimental values except e.
