A physical model to express grain boundaries in grain growth simulation by phase-field method
晶粒生长演变相场法模拟界面表达的物理模型

Grain boundary model in phase-field simulation during microstructure evolution in solid states is discussed based on the way to express grain boundary and its physical background.The effects of different values of simulation parameters on feature of grain boundary in the phase field model are investigated systematically and a new conception of grain boundary range is suggested based on the simulation results of recrystallization of AZ31 magnesium alloy.The gradient range of the order parameter expresses the...
