摘要

利用Miedema及其同事提出的半经验生成热理论，建立了25种简单共晶二元合金的液相曲线。总的来说，这个理论的预测是相当正确的。在存在差异的情况下，可以通过保留Miedema提出的生成热的正式表达式，但修改溶液热的规定值来改进结果。

Construction of liquidus curves of simple-eutectic binary alloys from Miedema theory

The liquidus curves of twenty five simple-eutectic binary alloys are constructed using the semi-empirical theory of heats of formation developed by Miedema and coworkers. Overall the predictions of this theory are quite correct. In cases where discrepancies exist, it is possible to improve the results by retaining the formal expression of the heat of formation proposed by Miedema, but modifying the prescribed values of the heats of solution.
