摘要

In this study, two of the severe plastic deformation (SPD) techniques, equal channel angular pressing (ECAP) and multi-axial compression (MAC) have been successfully applied to the Al-6061 alloy and the development of microstructure, texture and mechanical properties have been studied. It was found that the MEM (MAC+ECAP+MAC) and MEE (MAC+ECAP+ECAP) can effectively refine grains and hinder the movement of dislocations. The mechanisms of continuous dynamic recrystallization operating during severe deformation are discussed in the detail. The tensile strength and the macro-hardness of alloy after MEM and MEE deformation was increased. Refined grain and dislocation aggregation were mainly dedicated to the improvement of alloy mechanical properties.
