ABSTRACT:
A magnesium alloy exhibiting high strength and high ductility, characterized in that it comprises 0.03 to 0.54 atomic % of certain solute atoms belonging to 2 Group, 3 Group or Lanthanoids of the Periodic Table and having an atomic radius larger than that of magnesium and the balanced amount of magnesium, and has a fine crystal grain structure wherein solute atoms having an average crystal grain diameter of 1.5 μm or less and being unevenly present in the vicinity of crystal grain boundaries at a concentration being 1.5 to 10 times that within crystal grains, wherein an atom selected from the group consisting of Ca, Sr, Ba, Sc, Y, La, Ce, Pr, Nd, Pm, Sm, Eu, Gd, Th, Dy, Ho, Er, Tm, Yb and Lu can be used as the above solute atom; and a method for producing the magnesium alloy. The above magnesium alloy is novel and achieves high strength and high ductility at the same time.
