Al-Mg-Si alloys (6xxx series alloys) have been classified as an age-hardenable alloy.Addition of transition metals to Al-Mg-Si can improve the mechanical properties due to effect of grain refinement.Also, amount of Si is important for mechanical properties.In this research, Al-1.0％Mg2Si-0.4％Si [mol％], (excess Si-type Al-Mg-Si alloy) with Cu and without Cu prepared by casting to investigate the effect of alloying elements Cu and Si.Solution treatment was conducted at 848 K for 3.6 ks.Cold rolling was conducted with the thickness reduction of 0, 10, 30 and 60％ after solution treatment.After deformation, samples were subjected to aging treatment at 473 K.Vickers microhardness measurement was conducted.Microstructure was observed using TEM.
