摘要 参考文献 相关文章 Metrics 全文: PDF(415 KB)   摘要: 将过剩自由能表达为组元的多项式函数。以该体系液相区边界条条件为基础,用拟合法确定碳偏mole自由能表达式中的参数,然后,用“I—D”法给出组元X的活度系数,此法可以确定各C—Fe—X系整个液相区中任一组元的活度,解析结果与文献上的试验结果吻合得很好。 关键词 ： 组元活度系数,  C-Fe-Mn系,  C-Fe-Si系,  C-Fe-Cr系,  C-Fe-Ni系     Abstract：The parameters in the polynomial expression of partial mole free energy of Cwere evaluated by value fitting method on the basis of boundary conditions of liquid domainon the system C-Fe-X(X=Si, Mn, Cr, Ni). Then the activity coefficient of the element Xmaybe calculated with the I-D method. The approach suggested is proved to be useful for theactiveity evaluation of every element in the whole liquid domain of the concerncd 4C-Fe-Xternary systems. The results are found in a good agreement with those of citedprovious literatures.
