| چکیده | ||
| In this research, a new technique for severe plastic deformation (SPD) was proposed, entitled as non-uniform simple shear extrusion (NUSSE). The larger strains can be obtained in the non-uniform simple shear extrusion (NUSSE) method without repetition of the process. But, in pure shear extrusion (PSE) and simple shear extrusion (SSE) processes, to achieve larger strains, it is necessary to repeat the processes. In this study, the technique was investigated experimentally and numerically using ABAQUS software. The maximum plastic strain, inhomogeneity in deformation, filling fraction and micro-hardness parameters were researched after NUSSE process. Also, the obtained results were compared to the SSE and PSE processes. After this technique, due to the specific design of deformation channel, filling fraction was increased by about 44.92% and 41.84% in comparison with SSE and PSE processes, respectively. Also, the micro-hardness was significantly increased compared to annealing process. | ||
