Abstract

The cellular automata (CA) model combining topological deformation and adaptive activation energy was successfully constructed to analyze the thermal dynamic recrystallization of the magnesium alloy (AZ61). The simulation datum shown that the recrystallization nucleation located on the grain boundary (GB) once the density of dislocation accumulated to specific value, and the result presents a typical characteristics i.e., repeated nucleation and growth. The simulation results agree well with the experimental results because the activation energy affects recrystallization by affecting nucleation rate.

结合自适应活化能和基体变形拓扑的元胞自动机方法模拟镁合金动态再结晶

建立了结合拓扑变形和自适应活化能的元胞自动机(CA)模型，分析了镁合金(AZ61)的热动态再结晶过程。模拟数据表明，当位错密度累积到一定值时，再结晶形核位于晶界处(GB)，其结果呈现出典型的反复形核长大特征。模拟结果与实验结果吻合较好，因为活化能通过影响成核速率来影响再结晶。
