چکیده مقاله
In most processes of severe plastic deformation, including in the aboveprocesses, the strain distribution is inhomogeneous, which causesmechanical instability in the parts In the SSE process, the strain rate atthe center of the material is higher than the friction surfaces, whereasthis strain distribution is reversed in the CEE process In the researchconducted by combining the SSE CEE processes first the SSE processand then the CEE process and vice versa, the strain distribution issignificantly homogeneous in the sample and it can be suggested as away to obtain a homogeneous material with mechanical stability In thisstudy, DEFORM and ABAQUS finite element software were used toobtain the strain distribution in the consumed material The results showthat the strain distribution homogeneity factor in SSE and CEE processsamples was 1 5 and 3 8, respectively, which is 6 5 and 9 8 inCEE SSE and SSE CEE process that shows a significant improvementin homogeneity
