Abstract: A new serve plastic deformation (SPD) including initial forward extrusion and subsequent shearing process (ES) was proposed. The influence of the ES forming on the grain refinement of the microstructure was researched. The components of ES forming die were manufactured and installed to Gleeble1500D thermo-mechanical simulator. The microstructure observations were carried out on the as-extruded rods (as-received) and ES formed rods. From the simulation results, ES forming can increase the cumulative strain enormously and the volume fraction of dynamic recrystallization. From the physical modeling results, the microstructures can be refined.
