"Equal Channel Angular Extrusion" (ECAE) is a significant method in industrial forming applications, which is the most important method for the production of ultrafine grained bulk samples, where plastic strains are introduced into the bulk material without any changes in the cross section. ECAE has different die channel angles from which an optimum die channel angle should be identified so that efficient mechanical properties will be obtained. This study is focused on the plastic deformation behavior of Al alloys by modeling ECAE with experimental and finite element software. A solid model...
