Abstract

A challenge for the research and industrial community is to develop lightweight wrought Mg-based alloys that exhibit high strength and good ductility. To address this challenge, Mg-3Sn-2Al (TA32) alloy was produced by the squeeze casting process followed by hot rolling (HR). To improve its ductility, the hot-rolled alloy was annealed (HRA). HR and HRA samples were subjected to microstructural, composition, textural, and mechanical property analysis. The HR sheet exhibited high strength with 0.2 proof stress (PS) of 274 MPa and ultimate tensile strength (UTS) of 390 MPa, as well as reasonable ductility (12) along the rolling direction, one of the highest values for Mg alloys. HRA sheet showed a moderate reduction in strength with a 0.2 PS of 250 MPa and UTS of 365 MPa, but an improvement in ductility (19). The excellent properties of this alloy can be attributed to the synergistic effects of grain refinement, solid-solution strengthening by Al and Sn atoms, and uniform distribution of fine Mg2Sn particles. © 2021, The Minerals, Metals & Materials Society.
