An experimental Al-7.32wt%Si-0.3wt%Mg alloy equivalent to cast A356 Al-Mg-Si alloy was studied. Age hardening was performed by two artificial ageing heat treatments, T6 and T6I6. Vickers microhardness was measured within the dendritic regions. It was found that peak ageing was reached after about 24...
