摘　　要：基于Monte Carlo方法所建立的退火模型,以一种含Nb的冷轧超低碳高强度烘烤硬化钢板(简称ELC-BH钢板)为研究对象,进行了退火组织演变的模拟和实验研究。结果表明:模拟结果较好地反映了ELC-BH实验板退火组织演变过程,特别是展示了回复阶段再结晶孕育期,证实了该模型的合理性和实用性;考虑升温、亚晶形成、析出相粒子等影响来进一步改进模型,可改善其实用效果。Based on an annealing model established by Monte Carlo method,the simulation and experimental research on annealing microstructure evolution of a Nb bearing cold-rolled extra low-carbon high strength and bake hardening（ELC-BH） steel sheet were carried out.The results show that the simulation results well reflect the annealing microstructure evolution of the experimental sheet and demonstrate the recrystallization incubation time in the recovery stage,which confirm that the annealing model has great validity and practicability.Considering the effects of rising temperature,subgrain forming and precipitation particles,the model can be further modified to improve its usability.
