In this paper, an Al-Mg-Si-Cu aluminum alloy was exposed to various heat treatment processes and the effect of precipitation hardening on hardness was investigated as a function of time and temperature. It was concluded that the variation in time and temperature can improve the hardness of the alloy
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 180Β°C serrated yielding was not observed. The strai
