Effects of Equal Channel Angular Pressing and Heat Treatment on Low Cycle Fatigue Properties of 6005 Al Alloy
The effects of equal channel angular pressing (ECAP) and subsequent heat treatment on the low cycle fatigue properties of 6005 Al alloy were investigated. The ECAPed specimens showed cyclic softening, whereas the peak aged specimens showed cyclic hardening at all strain amplitudes. After ECAP, artificial aging was performed at 175°C to observe the change of the low cycle fatigue properties due to precipitation. The fatigue life and behavior of the unECAPed and ECAPed 6005 Al alloys were discussed in terms of the microstructural changes and aging conditions.
