Strain and temperature gradients are developed through the cross-section during the hot rolling of steel rods. These gradients are of particular interest because of their potential effects on the homogeneity of the resulting microstructure during rolling as well as in the final product. Strain and temperature can strongly influence recrystallization and transformation behaviour. / A three-dimensional, temperature-dependent viscoplastic finite element analysis was used to predict the strain distribution developed for the hot rolling of steel square billets using the software package ABAQUS/EXPLICIT$ sp{ rm TM}.$ Constitutive parameters were determined from previous experimental data generated at McGill University and at the Metals Technology Laboratory (MTL), CANMET. / McGill-CANMET's Property Prediction Model was used to determine the microstructure during rolling and the final properties at room temperature. / Results from the mechanical and microstructural models were validated with experimental data from literature and from rolling tests performed at MTL-CANMET. / With these two models, several different hot rolling scenarios were generated to examine how the two models would predict their results by varying a single parameter.
