摘 要: 利用Monte Carlo方法模拟了300×300×300三维正常晶粒长大过程，研究密排六方点阵的应用可行性及其特点，比较不同点阵结构以及不同范围的近邻结点的能量计算对晶粒长大过程的影响。通过综合分析晶粒长大动力学和拓扑结构发现，密排六方的点阵结构以及考虑更大范围近邻结点的能量计算方式更适合正常晶粒长大过程的模拟。

Abstract:A 300×300×300 three-dimensional normal grain growth was simulated by using Monte Carlo method. Different lattice types and energy calculations considering different neighboring sites ranges were compared. It could be found that the triangular lattice and energy calculations considering a wide neighboring sites range are much more appropriate to simulate grain growth by comprehensive analyzing grain growth dynamics and topological microstructure.
Key words: grain growth; Monte Carlo; three-dimensional; simulation; triangular
