查询词典 boundary surface

In order to improve present Monte Carlo methods, method changing the node to optimistical orientation corresponding to the system having the lowest energy was proposed, which ensures the grain boundary moving to its curvature center. The new method avoided re-nucleation, and increased simulation efficiency, and made the simulation process more approaching the physics foundation of grain growth. The results show that the grain growth exponent, n=0.478, is close to its theoretic value, and the topological structure accorded with the normal grain growth of the real material.

简要回顾了晶粒长大理论并分析了现有Monte Carlo模拟方法的不足，提出了一个"择优转换"方法，确保节点转换时晶界向其曲率中心移动，以致模拟过程更接近物理基础，避免了重新形核的发生，使模拟效率大大提高，模拟的晶粒长大指数达到0.478，已接近理论值，组织形貌和实际材料正常晶粒长大组织基本一致。
