摘要
根据含化合物金属熔体的共存理论和Fe-Al系相图,用回归分析法确定了Fe-Al系金属熔体在1315℃和1600℃时的结构单元,进而推导了各组元的作用浓度模型。将计算的N_(Fe),N_(Al)和实测的活度值α_Fe,α_Al相比较,得到了比较满意的结果。
In accordance with the coexistence theory of metallic melts structure involving compound formation and Fe-Al phase diagram as well, and by means of regression analysis, the structral units of Fe-Al melt at 1 315℃ and 1 600℃ have been determined. On the basis of these structural units, the calculating models of mass action concentrations have been deduced. The agreement between calculated values of NFe, NAl and measured ape, aAl respectively is satisfactory.
