摘要
基于晶界能和晶界曲率的晶粒生长驱动力理论,建立了温度场影响下二相粒子晶粒生长的元胞自动机模型。对二相粒子SiC在镁合金激光合金化中晶粒生长过程进行了模拟。结果表明,模拟过程稳定,模拟结果与其微观组织相吻合,建立的元胞自动机模型适用于SiC颗粒在镁合金激光表面合金化的晶粒生长过程。
According to the grain growth driving force theory of grain boundary, a grain growth simulation model for SiC in laser alloying process of magnesium alloys was established based on cellular automata. The grain growth process of two-phase particle SiC in laser alloying of magnesium alloy was simulated. The results show that the simulation process is stable, and the simualtion results are in good agreement with the microstucture of SiC materials. The cellular automata model is applicable to the grain growth simulation of magnesium alloy in laser alloying process.
