Abstract

See full text

The present invention provides a shape-memory alloy including a Au—Cu—Al alloy having 20 at % or more and 40 at % or less Cu and 15 at % or more and 30 at % or less Al, with the balance being Au and inevitable impurities. The shape-memory alloy has a Vickers hardness of 360 Hv or less. The Au—Cu—Al alloy of the present invention is an alloy capable of developing both biocompatibility and a shape-memory effect, and further capable of achieving artifactlessness in a magnetic environment. The Au—Cu—Al alloy can be produced by heat-treating a clad material formed of a combination of a hollow material made of a Au—Cu alloy and a core material made of metallic Al at 500° C. or more and 700° C. or less.
