Calculation of Activities from Phase Diagrams Involving Solid Solution
-
摘要: 本文提出了一種由固溶體類型的二元相圖提取組元活度的新公式。在該式中各組元的活度系數可以表示為組成的函數。用此公式對Ag-Pb體系進行了計算,證明了該方法是有效的。Abstract: The Analytical expressions for calculating and activity coefficients at a fixed temperature from phase diagrams involving equilibrium between solid and liquid solutions are derived. In the expressions, activities and activity coefficients are functions of the composition. These expressions are applied to system Ag-Pb, and the results are efficient.
