Microstructure and Tensile Properties of a Mg-5Sn-4Al Alloy

Article Preview

Abstract:

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 a-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.
