Study on the Recrystallization of Deformation Microstructure of AZ31 Magnesium Alloy


Article Preview

A real-time calculation model discretized by the cellular automata (CA) method was developed for the numerical simulation of AZ31 magnesium alloy microstructure evolution during recrystallization (RX). The RX processes under different strains were simulated, also, variations in morphologies of recrystallization grains are discussed. The results of numerical simulation were compared with those of experiment analysis, and the microstructure obtained by CA was found to well agree with the actual pattern obtained by EBSD (Electron Backscattered Diffraction) analysis. The numerical simulation technique provides a flexible way of predicting the recrystallization of deformation microstructure evolution.
