摘要
测定了不同温度下碳在Mn液中的溶解度和碳在Si Mn合金液中1350℃的溶解度。同时又测定了1350℃ Ca在CaC_2坩埚内Mn-C合金液的溶解度。利用实验数据求出e_C^(Si),e_C^C,e_C^(Ca)及Inγ_C^0,并计算出碳在Mn液中的标准溶解自由能及其与温度的关系式。
The solubility of C in Mn melt at different contents of Si at 1350℃was determined. The solubility of Ca in Mn melt containing C in CaC_2 crucibleunder sealed condition at 1350℃ was ascertained. With these data, evaluation ofthe activity interaction coefficients e_C^(Si), e_C^(Ca), e_C^C as well as γ_C^O was made. The standardfree energy of solution of C in liquid Mn based on the 1 wt-% solution standard,formulated in relation to T, was also estimated. Brief discussion was made as tothe confirmability of results with those given in the literature.
