Effect of a short solution treatment time on microstructure and mechanical properties of modified Al–7wt.%Si–0.3wt.%Mg alloy
TL;DR: In this article, the impact energy of a strontium modified Al-7wt.%Si−0.3%Mg cast alloy was studied and it was found that a solution treatment of 10 min at 540 or 550 °C is sufficient for the α-aluminium phase to homogenise and achieve the maximum level of magnesium and silicon as predicted by the solubility and alloy composition limits.
