对现有Ag-Ge合金相图的液相线进行了热力学分析,得到Ag-Ge液态合金的过剩摩尔自由焓随成分变化的四参量表示式。计算得到:当x_(G)·<0.25时,混合热H~M<0,当x_(G)·>0.25时,H~M>0,说明原子间交互作用强烈与成分有关。对实验尚未准确测定的Ag基固溶体的固相线进行了计算。 Thermodynamic analysis of the liquidus of the existing Ag-Ge alloy phase diagram was performed to obtain the four-parameter expression of the excess molar free enthalpy of the Ag-Ge liquid alloy as a function of composition. The results show that when x_ (G) · <0.25, the mixed heat H ~ M <0. When x_ (G) ·> 0.25, H ~ M> 0, indicating that the interaction between atoms strongly depends on the composition. The solid phase of the Ag-based solid solution, which has not been measured experimentally, has been calculated.
