摘要
针对液态合金提出以正规溶液作为判断实际体系对称性的热力学基准,将Toop法、周国治法、Kohler法以及新一代几何模型4种几何模型应用于10个液态合金体系的活度预测,比较预测效果的差异。结果表明,采用正规溶液模型作为判断实际体系对称性的热力学判据是方便可靠的。在4种模型中,Toop模型预测效果最好,所需参数最少。新一代几何模型(Chou’)预测效果较好,所需参数最多。Kohler和周国治(Chou)模型预测效果相对较差,所需参数数量较多。
A thermodynamic criterion for identifying the symmetry of ternary liquid alloy systems with regular solution is described. Toop, Kohler, Chou and Chou' models are applied to activity prediction for ten liquid alloy systems, and the predicted effects are compared. The results show that among predictions of 4 models, Toop′s is the best and parameters needed are the least, Chou' is better in results and more parameters needed than that Kohler and Chou models.
