Abstract


In the present work the mechanical properties of the alloy AlSi7Mg were studied in order to choose a suitable composition and heat treatment for sand castings. The mechanical properties have been evaluated varying the content of Mg, covering the alloys A356 and A357. The effect of heat treatment has been studied in alloy A356 varying the emperature and time of the precipitation heat treatment, while the dissolution treatment was kept constant. Several quality indexes have been defined which combine tensile strength, yield strength, tensile strength and elongation in order to select an adequate chemical composition and heat treatment for each application.
