چکیده انگلیسی
A new method for severe plastic deformation is proposed herein, entitled as Simple Shear Extrusion (SSE) due to the manner in which specimen's cross-section shape changes. This method is based on pressing material through a specially designed direct extrusion die. The process was investigated experimentally on commercially pure aluminum. Additionally, simulation of the process was also carried out, using the commercial finite element code ABAQUS/Explicit. Moreover, effect of back-pressure on the results was studied. Results show that SSE method is capable of imposing high strain values via strain accumulation during repeating the process, which is of great importance in producing ultrafine-grained or nanostructured materials.
