稀土族Pm和Tm两元素固溶度的抛物线法预测

Prediction of the Solid Solubility of Binary Alloys Based on Pm,Tm Metals Using Parabola Method

本文利用张邦维等提出的键参数函数和尺寸因素方法对稀土族Ｐｍ、Ｔｍ两元素基上的室温下固溶反作抛物线法预测．对２３个过渡族基、１８个简单元素基、１３个稀土族元素基和３个锕系元素基的研究所得结果与实验测定数据很好地符合，因此，预测结果是可信的．

In this paper the bond-parameter function, size factor ,and therefore theparabola method proposed by one of the authors(Zhang Bangwei) are used to predict thesolid solubilities for binary alloys based on Pm and Tm metals. It is believed that theprediction is reliable because the theoretical research resuults based on 18 non-transitionmetals ,23 transition metals,13 rare earth metals and 3 actinide metals are in good a-greement with the experiments.
