MAGNESIUM ALLOY THAT EXHIBITS SUPERELASTIC EFFECT AND/OR SHAPE-MEMORY EFFECT

摘要

An object of the present invention is to provide a Mg alloy that exhibits a superelastic effect and a shape memory effect, and is excellent in cold workability. The Mg alloy is prepared so as to have a composition in which Sc is contained in a content of more than 13 at% and 30 at% or less, and the balance is Mg and inevitable impurities. In addition, the alloy may contain, in addition to the above-described composition, at least one or more additive elements selected from Li, Al, Zn, Y, Ag, In, Sn and Bi, in a total content of 0.001 at% or more and 9 at% or less in relation to the amount of the whole alloy defined to be 100 at%.
