摘要： 金属再结晶过程计算机组织模拟,可以仿真实验中观测不到的组织演变细节,得到定量的特征参数,预报退 火后的材料性能,指导热处理工艺设计。构建一个新的静态再结晶MCPotts模拟模型,并以1060铝合金为研究对 象,进行再结晶模拟与实验对比研究。结果表明,1060铝合金表现出明显的再结晶特征,得到了近似等轴晶组织; 新模型模拟的再结晶形核位置、组织形貌与实验结果一致,组织演变过程也与实验结果基本一致,但模拟的再结晶 等轴晶与实验近似等轴晶不完全一致,模拟的再结晶速度也低于实验结果。

Abstract: The simulation of metal re-crystallization by computer could simulate the details of microstructure evolution which can't be observed in experiment. Meanwhile, the quantitative characteristic parameters are obtained, and the properties of material after annealing are also forecasted, which can guide the heat treatment process design. A new MC Potts simulation model is constructed, and is used to simulate the static re-crystallization behaviours of 1060 aluminum alloy. With the simulation, an experimental study is also carried out for comparison. The results show that 1060 aluminum alloy presents significant re-crystallization characteristics, and an approxim ately isometric crystal organization is obtained in the re-crystallization experiment. The simulation results of re-crystallization nucleation location and microstructure morphology got by this model are consistent with experimental results, and the evolution process of crystal structure is also consistent with experimental results generally; however, the simulated isometric crystal organization is not exactly consistent with approximately isom etric crystal organization by experiment, and the velocity of re-crystallization by simulation is also lower than that by experiment

Key words: re-crystallization, simulation, Monte Carlo
