In this paper, the basic theory and work principle of cellular automata were introduced concisely. The influence of strain-rate and temperature on the number of nucleation and the mean size of R-grain, as well as the influence of cooling on ultimate microstructure of blade after forging finished off were considered. The microstructure evolution was simulated successful based on the DEFORM-3D. The simulated results agree well with growth kinetics of dynamic recrystallization of classical theory and physical experiment.
