Effects of Zn and Sn Additions on the Mechanical Properties of Mg-3%Al Alloy
A small amount of Zn or Sn was added to Mg-3%Al alloy to improve the formability of alloy. The elongation of as-rolled alloy was increased at both room temperature and 300oC by addition of Sn or Zn, even though the tensile strength at room temperature was remarkably increased only by Zn. When the as-rolled alloy was annealed to be fully recrystallized, the ductility at room temperature was significantly enhanced, however the elongation at 300oC was rather decreased probably attributed to the dynamic recrystallization occurred during the tensile test.
