This article investigates the simultaneous  efect of extrusion ratio and T6 heat treatment on microstructure and mechanical properties of in-situ Al-15wt.%Mg 2 Si composite. his composite has already been introduced as a new class of light materials but the brittle structure of the primary Mg 2 Si which is formed during solidiication limits its application. As-cast composite was directly extruded as rod by using three diferent dies. Ater 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 as-cast samples. It was also found that heat treatment and extrusion processes change the primary Mg 2 Si morphology considerably and its size increases as extrusion ratio decreased. Fracture surface examinations revealed a transition from brittle fracture mode in as-cast composite to ductile fracture in heat treated and extruded specimens. his can be attributed to the changes in size and morphology of Mg 2 Si intermetallics and porosity content.
