Abstract:Based on the cellular automata (shortly called CA) made up of Moore neighbor type and its translation rules, the variation of shape and size of three kinds of single and smaller grains was simulated in the process of grain growth. The grains are quadrilateral, hexagonal or octagon surrounded with a few grains, respectively. The results show that the changes of grains correspond to the general law of grain growth, that is, as extending the progress of grain growth, the grain whose boundary is more than six continues to grow and its boundary number approaches six, and the grain whose boundary is less than six continues to diminish until disappear. The model used has better physical basis to suit for simulating the progress of grain growth.
Key words: cellular automata; grain growth; computer simulation
