Effects of Zn and Sn additions on the mechanical properties of Mg-3%Al alloy

A small amount of Zn or Sri 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 300 degrees C by addition of Sri 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 300 degrees C was rather decreased probably attributed to the dynamic recrystallization occurred during the tensile test.
