Modelling of Recrystallization and Grain Boundary Migration by Cellular Automata

Abstract. Within past ten years, the importance of cellular automata (CA) models of both recrystallization and grain boundary migration has been recognized. It can be shown that CA provides a computationally efficient mathematical framework for simulations of physically relevant models of the above processes. Generally, CA works in such models with a vast number of identical copies of several generic processes -as recrystallization, nucleation, grain boundary migration, etc. -which interact locally and results in a complex global response. The attention is focused to some important aspects of recrystallization, grain growth and CA modelling. Finally, possible future development of more physically relevant models are briefly outlined
