最近由MacPherson和Srolovitz提出的三维颗粒生长速率方程表明，颗粒体积的变化率取决于颗粒的平均宽度和三重线的总长度。本文采用大型Potts模型-蒙特卡罗模拟方法对该速率方程进行了研究。结果表明，平均晶粒长大速率数据与MacPherson-Srolovitz三维晶粒长大速率方程符合得很好，从而对该速率方程进行了初步验证。
MacPherson-Srolovitz's three-dimensional grain growth rate equation proposed recently by MacPherson and Srolovitz indicates that the change rate of grain volume depends on the mean width of grains and the total length of the triple lines. This rate equation is studied by large-scale Potts model-Monte Carlo simulation in this paper. The result shows that the data of averaged grain growth rate fit the MacPherson-Srolovitz’s three-dimensional grain growth rate equation very well, thereby this rate equation is preliminary verified.
