摘要：
While conventional equal channel angular pressing (ECAP) has been widely investigated as the prominent severe plastic deformation method, no detailed work has been carried out on the modified ECAP techniques. So, this work deals with the numerical characterization of 7075 aluminum billet processed by conventional and modified ECAP methods. It has been found that T-shaped ECAP is the best technique to choose from the effective plastic strain point of view. Also, the highest plastic strain distribution uniformity and concomitant least required pressing load belong to the cross-ECAP condition. Moreover, conventional ECAP process should be selected if the minimum temperature rise and damage have been considered. Eventually, shear plane mode of oblique, V-shape, and X-shape is attained for the conventional, T-shaped, and cross-ECAP conditions, respectively.
