Abstract

The effect of ageing temperature on the mechanical properties of Al-Mg-Si alloy has been studied. The material was machined into different shapes of the tests to be carried out: tensile, impact and hardness. The test specimens were divided into two and, some sets were solution treated at 500℃ for one hour and peak aged at 160℃ for eight hours while the other sets were solution treated at 500℃ for one hour and peak aged at 180℃ for eight hours. The abovementioned tests were carried out on the specimens. The results show that at low ageing temperature of 160℃, the ductility and impact were high while at 180℃, the ultimate tensile strength and hardness are higher compared to the value obtained at 160℃.
