Mesoscopic Simulations of Recrystallization and Grain Growth in a Fe-0.374C-21.64Mn Alloy

摘要

A cellular automaton and a vertex model were used, respectively, for the simulation of re-crystallization and grain growth in a Fe-0.374%C-21.64%Mn alloy. The results of the recrystallization simulations revealed that the preferential nucleation during the annealing of the rolled sheet occurs at shear bands, which is corroborated by experimental observations. Subsequently, grain growth simulations were carried out with a 2D vertex model. The model used experimental data as input for its validation in this specific steel. The simulations showed a good agreement with the experimental results.
