Analyzing the Microstructure and Tensile Properties of an Al8Si0.35Mg Cast Alloy with Prolonged Aging
This paper examined the microstructure and tensile properties of an Al8Si0.35Mg cast alloy during several prolonged aging treatments. The results show that there is a improvement in ductility for solution treated Al8Si0.35Mg samples aging at 150 °C more than about 20 h to 48 h or ageing at 200 °C more than about 10 h to 20 h, but no significant reductions in UTS are observed. There is a substantial improvement in ductility at long aging times at the cost of UTS decreases. The morphology changes and distribution characteristics of precipitates and its effect on tensile properties in prolonged aging conditions have been analyzed.
