摘要: This paper explores the possibility of developing an Al-Mg2Si-Mg-Zn based sand cast alloy having improved mechanical properties. The effect Zn and free Mg after combining with Si to form Mg2Si on microstructure properties was investigated under as-cast condition. Eight different alloys were prepared by varying Mg(4.15 – 12.0 wt.%) Zn(2.58 6.22 contents 0.2 proof strength, tensile elongation at failure hardness measured microstructural investigation conducted optical microscopy all found contained α-Al, Al-Mg2Sieutectic Mg2Siphases. addition generally improves strength decreases elongation, while shows a peak for between range 3 6 wt.%. Addition content also has similar in improving decreasing ductility. Comparing alloys, 3having 5.41wt.%Mg, 1.85%Si 5.45%Zn best combination
