    • Provided is an Mg alloy and a method for producing same able to demonstrate high strength without requiring an expensive rare earth element (RE). The high-strength Mg alloy containing Ca and Zn within a solid solubility limit and the remainder having a chemical composition comprising Mg and unavoidable impurities is characterized in comprising equiaxial crystal particles, there being a segregated area of Ca and Zn along the (c) axis of a Mg hexagonal lattice within the crystal particle, and having a structure in which the segregated area is lined up by Mg3 atomic spacing in the (a) axis of the Mg hexagonal lattice. The method for producing the high-strength Mg alloy is characterized in that Ca and Zn are added to Mg in a compounding amount corresponding to the above composition and, after homogenization heat treating an ingot formed by dissolution and casting, the above structure is formed by subjecting the ingot to hot processing.
