Strength of aluminum alloys can be remarkably improved by obtaining ultrafine grain size via severe plastic deformation. Equal Channel Angular Pressing (ECAP) is considered to be a good candidate that is capable to produce bulk components. In this study, the combined effects of ECAP and post-aging treatment on the mechanical properties of aluminum alloys were investigated. An ECAP die with 120 degrees channel angle was used for severe plastic deformation of 2024 Al-alloy. The ECAPed specimens revealed higher hardness values after post-aging at 190 degrees C.
