Equal Channel Angular Extrusion (ECAE) is the most popular method of metal forming process having severe plastic deformation with the capability of producing ultra-fine grain structure in materials. In this study, the finite element simulation of ECAE process was carried out using standard software in order to investigate the combined effect of temperature and friction on strain inhomogeneity for Aluminum 6082 ZrSc alloy for three different channel angles and two different billet sections. It was found that, for lower coefficient of friction, strain homogeneity for rectangular shaped billet is better than the cylindrical shaped billet even at high temperature. Higher coefficient of friction can be suggested only for cylindrical shaped billet at elevated temperature.
