| 摘 要： | 以物质守恒方程，液固界面平衡方程为基础，提出一个反映多元合金系中组元间相互作用的凝固模型，并从应用的角度出发，对该模型进行了合理的简化，利用这个模拟对合金元素在多元Ａｌ－Ｃｕ系合金凝固过程中的行为进行计算模拟，所得的情况与实验结果相一致，表明这个多元系凝固模型可以为多元Ａｌ－Ｃｕ系合金化设计作出有效的预测。

| Abstract: | Based on mass conservation equation and interface equilibrium equation for liquid and solid, a multicomponent solidification model that reflects the component interactions in the multicomponent alloy system is provided. The model was simplified reasonably from a view of application and used in simulatation of the solidification behaviors of alloy elements in the multicomponent Al- Cu alloy. The results obtained are identical with the experiment, indicating that this model can put forward an available prediction in the alloying design of the multicomponent Al-Cu alloy. |
