Effect of Post-ECAP Aging on Mechanical Properties of Age-Hardenable Aluminum Alloys

Abstract:

Article Preview

Equal-channel angular pressing (ECAP) is an efficient method of improving strength of metallic alloys through (sub) grain refinement to, typically, the sub-micrometer level by introducing intensive plastic strain into materials through repetitive pressing. In the present study, the post-ECAP aging effect on strength of age hardenable aluminum alloys (6061, 2024, 7075 Al) was examined and it could be concluded that pre-ECAP solid solution treatment combined with post-ECAP low-temperature aging provided much more significant room-temperature strengthening effect than conventional ECAP processing routes without involving special heat treatments.
