Abstract

A magnesium alloy having high strength and high ductility and in which at least one of corrosion resistance and flame resistance is enhanced, or a method of manufacturing the same. The magnesium alloy contains an atomic % of Ca and b atomic % of Al, totally contains k atomic % of at least one element selected from a group consisting of Mn, Zr, Ag, Y and Nd, has a composition in which a remaining part is formed of Mg and contains c volume % of (Mg, Al)Ca, a, b, c and k satisfying formulae (1) to (4) and (21) below. The (Mg, Al)Ca is dispersed and the at least one element is an element that enhances at least one of corrosion resistance and flame resistance: (1) 3≤a≤7, (2) 4.5≤b≤12, (3) 1.2≤b/a≤3.0, (4) 10≤c≤35, (21) 0<k≤0.3.
