| 摘 要： | 实验测定了不同温度下，C在Mn-Fe熔体（x_Mn=0．0407-0．693 0，x_Fe=0．0336-0．7617）中的溶解度。根据Bale和Pehon提出的相互作用参数模型，利用文献报道的Mn-C系的热力学性质，使用测定的和文献报道的Mn-Fe熔体中C的溶解度值，以及文献报道的Mn-Fe-C熔体中Mn的活度系数值、MnO（s）和CO平衡Mn-Fe熔体的组成，通过热力学推导，实验数据处理和线性回归分析，得到Mn-Fe-C系ε_CFe，ε_CFeFe，εCCFe与温度T的关系式。

| Abstract: | Carbon solubility in Mn-Fe melts （x_Mn=0.040 7-0.693 0, X_Fe=0.033 6-0.761 7） was measured experimentally at various temperature. According to the unified interaction parameter model advanced by Bale and Pelton,utilizing thermodynamic properties in Mn-C system reported in references , using the carbon solubility in Mn-Fe melts obtained and reported in literatures, compositions of Mn-Fe-C melts equilibrating with MnO（s） and CO, by strictly thermodynamic derivation ,dealing with a lot of experimental data and linear regression analysis, the relationship equations between ε_CFe,εCFeFe,εCCFe and temperature in Mn-Fe-C system were obtained. |
