Abstract
In this study, a novel method for severe plastic deformation (SPD) was introduced, entitled as Combined SSE-FE (CSSE-FE). The process was investigated experimentally and numerically on AA1050 alloy. After this process, due to the unique design of the die channel, the sample significantly fills the die outlet channel. Also, the CSSE-FE process can produce large strains without repeating the cycle. Therefore, this parameter was increased by around 53.16 % in comparison to simple shear extrusion (SSE) process after the first pass. Also, microhardness was increased by about 87.93 % in comparison to annealed sample.
