Abstract

Parallel computation for moving boundaries in ceramic grain growth G.L. Ji\ Z.X. XiongZ, X. Fang', Z.C. Zeng' and X.H. Yang^ ^Department of Automation, Xiamen University, China ^Department of Materials Science & Engineering, Xiamen University, China Abstract Grain boundaries are moved while the average grain size becomes large during the grain growth process in ceramics. Therefore, the grain growth can be focused on the boundary moving. In this paper, a parallel computing method is applied to the simulation of grain growth. Compared with former work, computing speed is accelerated, more realistic images are obtained, and better quantitative results are reached. Based on the simulated results, a growth curve of S shape is found for the grain growth in ceramics. 1 Introduction Grain growth is a process by which the average grain size or area increases with time in a material, usually at high temperature. One of the most important driving forces results from the decrease in the tot
