A new FE-based analysis model for the microstructure evolution in hot rolling is proposed. Incremental formulations for the prediction of microstructure evolution are coupled with three-dimensional finite element method for the analysis of plastic deformation and temperature. By using an integrated FE-based model for the evolution of microstructure in hot rolling, cross-sectional grain size distributions after hot bar rolling are successfully simulated. Change in grain size of bar rolled by two-roll mill and three-roll mill, and microstructure evolution related to grain coarsening in bar sizing mill are shown and discussed.
