The influence of precipitation hardening on the characteristics of serrated yielding in an Al-IMg-Si alloy has been investigated. The critical strain at the onset of serrated yielding was increased by ageing and for ageing times longer than 6 hr at 180°C serrated yielding was not observed. The strai
Experiments were conducted to examine the influence of equal-channel angular pressing (ECAP) on the development of precipitation microstructures in two supersaturated Al-Zn-Mg alloys. The results show that ECAP leads to an ultrafine grain size with finely dispersed precipitates. It is concluded that
