The microstructural, mechanical behaviour of Mg-5Sn-3Zn-1Mn alloy with different Si additions (0.5, 1, 1.5 wt. % Si) are investigated and morphological changes of Mg-5Sn are observed with the addition of each element like 3Zn and 1Mn. Si added Mg-5Sn-3Zn-1Mn alloy exhibits two different phases namely Mg 2 Sn and Mg 2 Si. Two distinct phases observed are rod like Mg 2 Sn phase and Chinese script Mg 2 Si upto 1wt%. When Si addition exceeds 1.5% polygonal shaped primary Mg 2 Si particles are formed. In Mg-5Sn-3Zn-1Mn alloy addition of Si up to 1wt% enhances the mechanical properties adequately. Above 1 wt% of Si addition, a slight reduction on tensile property is noticed, which is due to the formation of hard, brittle polygonal primary and coarse Chinese script phases.
