Supersaturation behavior of Al solid solutions and its effect on tensile property in Al-7Si-0.4Mg and Al-7Si-0.8Mg alloys during solution heat treatment were investigated in this study. As a result of Mg solubility measurement for Al solid solitions after solution heat treatment for 6 hrs by electron probe micro analyzer (EPMA)-wavelength-dispersive X-ray spectroscopy (WDS), Al-7Si-0.8Mg alloy had the higher Mg solubility, about 0.55 mass%, corresponding to that of Al-Si-Mg ternary phase diagram. From the tensile test, Al-7Si-0.8Mg alloy showed the improved strength and similar elongation to that of Al-7Si-0.4Mg alloy.
