Grain Growth of AZ31 Magnesium Alloy Based on Three‐Dimensional Cellular Automata

Abstract: Based on the thermodynamic conversion mechanism and energy transition principle, a three-dimensional cellular automata model of grain growth is established from the aspects of grain orientation, grain size distribution, grain growth kinetics, and grain topology. Also, the effect of temperature on the three-dimensional grain growth process of AZ31 magnesium alloy is analyzed. The results show that the normal growth of three-dimensional grains satisfies the Aboav-weaire equation, the average number of grain plan… Show more

“…Comparing the simulation results with the experimental data, it is found that the simulation results of the equiaxed crystal region are close to the experimental data, but there is a relative error in the columnar crystal region. Li et al 22 established a three-dimensional CA model of AZ31 alloy grain growth based on the thermodynamic conversion mechanism and energy transfer principle, and finally confirmed the accuracy of the model. Wang et al 23 used a CA model based on a stochastic method to simulate the uniform corrosion and migration of metal elements in nickel-based alloys.…”
