Relationship between the microstructure and property of Al-0.21wt% Mg-0.41wt% Si alloy

In this study, the relationships between microstructure and property have been investigated for Al­ 0.21wt%Mg-0.41wt%Si alloy. JMatPro calculations was used to predict the phase relationships as a function of temperature. The effects of solution treatment (ST) and artificial ageing (AA) as well as n...
