Abstract : In this study, the effect of Sn addition on microstructure and mechanical properties of AS21 magnesium alloys. Sn additions were made by 1 and 2 wt%. Alloys were produced by conventional gravity casting. A pressure of 2 bar applied into the crucible and the melt was lifted into a steel mould preheated to 250 °C. Results showed that AS21 alloy consisted of -Mg grains and Chinese script type Mg2Si intermetallic phases. With increasing amount of Sn, -Mg grains and Mg2Si intermetallic phases were refined and the distribution of Mg2Si phase became more discrete and dense. AS21+1Sn alloy showed the best mechanical properties alloys with a yield strength of 118.9 MPa, an ultimate tensile strength of 203.2 MPa and an elongation of 7.2. The improvements in the strength and elongation were attributed to the refinement of -Mg grains and Mg2Si intermetallic phases.
