Effects of chemical composition and heat treatment on the microstructural and mechanical properties of cast Al-Mg-Si-Mn alloys were investigated. The as-cast and heat treated alloys were investigated by microhardness, macrohardness and tensile stress measurements, scanning and transmission electron microscopy, energy dispersive X-ray analysis and differential scanning calorimetry. It was observed that the mechanical properties depend strongly on composition and addition of excess elements and eutectic phase. Heat treatment leads
to the enhancement of all mechanical properties of alloys, which are the result of several mechanisms.
