摘要：
The microstructure and tensile properties at room temperature of as-cast, solution-treated and aged samples of a Mg-5Sn-4Al (wt%) alloy are investigated. The microstructure of the as-cast sample consists of alpha-Mg primary, Mg2Sn and Mg17Al12 divorced eutectic, secondary precipitations Mg17Al12 and Mg2Sn. After solution treatment, all the Mg17Al12 particles and the majority of Mg2Sn phases are dissolved into the matrix and the tensile strength and the elongation of the alloy increase obviously. During aging process many fine particles of Mg2Sn precipitate which result in the improvement of the yield strength.
