High-ductility magnesium–zinc–cerium extrusion alloys

A previous paper (Mishra et al., 2008 [1]) showed that the ductility of extruded Mg–0.2% Ce alloy is higher than that of magnesium and other conventional magnesium alloys. However, the strength of the Mg–0.2% Ce alloy was low. This study shows that a small addition of zinc (about 2%) can significantly improve the strength of the Mg–0.2% Ce alloy. The results showed that Zn increased strength through solid solution strengthening, and the Ce addition increased the ductility by providing a random texture in the extrusion.
