Mechanical properties of aluminium alloys processed by SPD: Comparison of different alloy systems and possible product areas

摘要

The mechanical properties of a wide range of aluminium alloys are compared after being subjected to severe plastic deformation (SPD), i.e. equal channel angular pressing (ECAP). Alloys involved are AlMg, AlMn, AlMgSi, and AlMgSc. The effect of SPD on mechanical properties is mostly beneficial with age-hardenable alloys, whereas non-age-hardenable alloys tend to be relatively less reacting to SPD as compared to conventional processing. Finally, some challenges in regard to commercialization will be discussed briefly.
