Abstract
This article investigates the simultaneous effect of extrusion ratio and T6 heat treatment on microstructure and mechanical properties of in-situ Al-15wt.%Mg2Si composite. his composite has already been introduced as a new class of light materials but the brittle structure of the primary Mg2Si which is formed during solidification limits its application. As-cast composite was directly extruded as rod by using three different dies. After T6 heat treatment on extruded samples, microstructure was studied by optical and scanning electron microscopy. Results demonstrated that extruded and heat treated composite possesses considerably higher strength and enhanced ductility in comparison with the...

Abstract
This article investigates the effect of T6 heat treatment on microstructure and mechanical properties of hot extruded in-situ Al-15wt%Mg 2Si composite. This composite has already been introduced as a new class of light materials but the brittle structure of the primary Mg 2Si which is formed during solidification limits its application. As-cast composite was directly extruded as rod by using three different dies. Microstructure after this type of extrusion was studied by optical and scanning electron microscopy. Results demonstrated that extruded and heat treated composite possesses considerably higher strength and enhanced ductility in comparison with the as-cast samples. It was also found...
