| Abstract: | We had discussed the mechanism of grain growth of polycrystalline materials and the methods of computer simulation in detail.In this paper,we propose a quick Q-state potts algorithm which based on Monte Carlo method and basic Q-state potts algorithm.Computer simulating on microstructure evolution of grain growth is accomplished by making program which written in Object Pascal language of Delphi 3.0 on a PC586.The dealing with our attained results are also done.The evolution figures of normal grain growth accord with the growth kinetics and the growth exponent we got is 0.47. |
