In this paper, deformation of 7075 Aluminum alloy in equal channel angular press/extrusion (ECAP/ECAE) is analyzed with using three dimensional (3D) simulation by finite element method. This investigation include effect of Die angle , number of passes, kinds of the routes(A,Ba,Bc,C paths), temperature of the process, and back pressure on equivalent strain and homogeneity of strain.
