Abstract: The improved site-saturated (ISS) mode and improved constant-rate (ICR) mode of nucleation were put forward on the basis of site-saturated (SS) mode and constant-rate (CR) mode of nucleation. A 2-D recrystallization model was developed to make crystal nuclei more uniform during recrystallization by coupling cellular automaton (CA) with Matlab. The effects of different modes of nucleation, neighborhood and boundary conditions on the kinetics of recrystallization, grain shapes and grain sizes were investigated. The results showed that the mode of nucleation affects greatly the kinetics but the neighborhood affects it unobviously. The final microstructures resulting from ISS and ICR modes present equiaxed grains and the grain size resulting from ISS mode is distributed most uniformly.
