引入θ参数导出由共晶相图提取活度的新公式

New Formulae for Calculating Activities from Eutectic Phase Diagrams after introducing θ

    摘要
  • 摘要: 借助于引入θ参数所得到的组元的活度系数与温度间的新关系式,导出了由二元简单共晶的相图计算组元活度的修正式。应用本文的新公式计算了1200K下Cu-Bi二元系中Cu-Bi的活度,结果表明经修正后的公式与实测数据吻合。

     

    Abstract: New formulae for calculating from simple eutectic binary phase diagram are presented, by introducing a parameter θ and leading to a new expression of activity coefficient with temperature. Using these new formulae, activities of Cu and Bi in Cu-Bi binary systemat
