摘　　要：根据Fe-C_(aat)-j三元系中a_c=1的性质,通过实验测定1400℃时j元素对碳溶解度的影响关系,结合已知的各一阶活度相互作用系数εf,求得相应的二阶活度相互作用系数。得到结果如下实验。According to ao =1 in Fe-C(Sat) -j ternary system, the effect of j element on the solubility of carbon in the melt was determined experimentally. In combination with the First-Order Interaction Coefficient ε pu-lished, the experimental results were obtained as follows: For Fe-C(Sat)-V system at 14002℃Nc =0.1937+0.4267Nv (Nv <0.075) ρcv=-4.081, ρccv=20.556, ρvc=-0.732, ρvcv=6.322 For Fe-C(Sat)-Nb system at 1400℃Nc =0.1918+0.8862NNb (NNb <0.035) ρcNb=-13.2258, ρCCN b=23.6016, ρNCb=-2.7958, ρNbC,Nb=-9.7453.
