The results show that, during the quasi-stationary state stage, the grain size distributions of the two microstructures seemly approach to a similar distribution, which is quite different from the Hillert (v=4) distribution.
设计两种可由不同参量的Weibull尺寸分布函数表达的晶粒组织作为初始态,采用Potts Monte Carlo方法对它们进行晶粒长大过程的仿真,结果表明,进入准稳态长大阶段后,两种组织的晶粒尺寸分布几乎同趋于另一种Weibull分布,而不是经典Hillert理论预测的Hillert(尺寸分布因子v=4)分布,该准稳态的晶粒尺寸分布也可用v<4的解析函数近似表示,从而为v<4的准稳态晶粒尺寸分布的存在提供了仿真实验证据。
