| 摘 要： | 利用Ｍｏｎｔｅ－Ｃａｒｌｏ方法，依据对金属凝固过程的温度场，浓度场的数值模拟和金属结晶过程中的热力学条件，建立了描述金属凝固组织形成过程的宏观－微观耦合模型，对Ａｌ－４．５％Ｃｕ（质量分数）固溶型合金的凝固组织形成过程进行了模拟，结果与实际凝固组织接近。

| Abstract: | The Monte Carlo simulation method for crystal growth is explored by including the macroscopic temperature, solute redistribution within the liquid phase and the thermodynamics in metal solidification process. A model coupling macro and micro is created to describe solidification structure formation in solidification process. The Al-4.5%Cu (mass fraction) alloy is used in the simulation. Finally, the simulation results are compared to experimental results. It shows that this simulation method is feasible. |
