Abstract

Al-Si-Cu-Mg casting alloys, having suitable physical and mechanical properties, are extensively applied in various industries such as Military, Automotive and Aerospace. The important microstructure controlling parameters are alloying elements, cooling rate and heat treatment conditions, which affect the mechanical properties of these alloys. The purpose of this research is the study of the effect of the amount of copper (0.1% to 2.5%) on the microstructure and mechanical properties of the alloy at various solidification rates, before and after T6 heat treatment. For this purpose, the samples were cast in the sand mould with various thicknesses (1,2,3,4 and 5cm) and with various percentages of copper. The results show that there are two opposite effects of copper on the mechanical properties of these alloys. On the one hand, formation of copper precipitations improved mechanical properties and, on the other hand, increasing porosities, due to copper, have an opposite effect on the mechanical properties. The alloy which contained 1.5% copper indicated optimum mechanical properties.
