Abstract

Following the previous development of Mg-Al-Sn alloys, the influence of Si on the microstructure and properties of Mg-Al-Sn alloys is investigated. Thermodynamic modeling of the Mg-Al-Sn-Si system based on the CALPHAD (CALculation of Phase Diagrams) approach was used to predict the microstructure and design the heat treatment schedules. Mg-Al-Sn-Si alloys were prepared by gravity casting using a cylindrical steel mold. The microstructure and mechanical properties of the as-cast and heat-treated samples were characterized and compared with those of Mg-Al-Sn alloys and against the predictions from thermodynamic calculations.
