Development of high ductility magnesium-zinc-cerium extrusion alloys

A previous paper [I] showed that the ductility of extruded Mg-0.2%Ce alloy is higher than that of magnesium and other conventional magnesium alloys. However, the yield and tensile strengths of the Mg-0.2%Ce alloy were low. The addition of aluminum to the Mg-0.2%Ce improved its strength but significantly decreased its ductility [2]. This study shows that a small addition of zinc (about 2%) can significantly improve the strength of the Mg-0.2%Ce …
