摘要
根据含化合物的金属熔体结构的共存理论，推导了１６７３Ｋ下Ｆｅ－Ｃ－Ｐ、Ｆｅ－Ｍｎ－Ｐ、Ｆｅ－Ｓｉ－Ｐ三元金属熔体作用浓度计算模型。计算的磷的作用浓度与相应的实测磷活度相符合，从而证明所得模型可以反映Ｆｅ－Ｃ－Ｐ、Ｆｅ－Ｍｎ－Ｐ、Ｆｅ－Ｓｉ－Ｐ三元熔体的结构本质。同时模型揭示了Ｃ、Ｍｎ、Ｓｉ的摩尔分数对磷的转换系数的影响规律。
According to the coexistance theory of metallic melt structure involving compound formation, a calculation model of mass action concentrations for Fe C P, Fe Mn P, Fe Si P metallic melts is formulated for T =1 673 K. Satisfactory agreement between calculated and measured value shows that this model can reflect the structural characteristics of the concerned metallic melts. Meanwhile, the model reveals the effect of X C, X Mn , X Si on L P.
