本文测定了1350℃时液态金属Ca在纯Mn液中和Mn合金溶液中的溶解度,并计算出Mn液中Al及Fe对Ca的活度相互作用系数。实验结果表明Al对Ca有很强的相互作用,使Ca的溶解度增加,而Fe却使Ca的溶解度下降。本文还就液态Ca溶于Mn液的标准溶解自由能进行了估算。
Solubility of Ca in manganese and manganese alloys was measured un-der sealed conditions at 1350℃. The interaction coefficients of Al and Fe on Cain Mn were evaluated with the experimental data. The standard free energy ofliquid Ca in liquid manganese based on thel wt-%. solution standard was estimatedas well.
