摘　　要：基于金属再结晶形核理论和实验基础,对现有再结晶Monte Carlo模拟形核模型进行改进,建立新的再结晶形核模拟新模型,并将之应用于高纯铝冷轧后等温退火过程模拟。结果表明,新模型有效地模拟了再结晶非均匀形核过程,模拟的形核顺序、形核率曲线与再结晶理论、实验结果一致。Based on metal recrystallization nucleation theory and experiments, a new nucleation model applied to Monte Carlo simulation was advised to improve the existing models. The results of cold-roll high purity aluminum annealing process simulation by Monte Carlo method showed that the new nucleation model could effectively simulate the heterogeneous nucleation in recrystallization process, and the nucleation order and nucleation rate curve consistent with the theory and experimental results.
