The invention relates to high ductility/strength magnesium alloys, particularly a magnesium alloy comprising up to about six weight percent zinc and up to about one weight percent cerium may be hot worked to produce an intermediate or final alloy workpiece that exhibits enhanced ductility and strength at room temperature. The addition of zinc and a small amount of cerium may affect the magnesium alloy by increasing strength and ductility, and improving the work hardening behavior.
