摘要
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.
