Cellular Automata Simulation of Grain Growth in Magnesium Alloy Heat Affected Zone of Laser Melt Injection

Abstract:

Based on the cellular automata (CAs) method of Moore neighbor type, a model of simulation for grain growth processes in magnesium alloy heat affected zone of laser melt injection was established. The results show that the grain growth process can be simulated very well by the CAs method, the shapes of grains tend to be hexagonal, the small grain is annexed by large grains, the grain growth index can be obtained as 0.42, and the topological feature reflected by the established model is accord with the physical mechanism of the grain growth. The cellular automaton (CA) method is proved to be a simple and effective approach for the grain growth simulation.
