Abstract
To remarkably improve shape memory properties without the need for strictly controlling the composition, the present invention provides a Ti--Ni-based shape-memory alloy having a titanium content within a range of from 50 to 66 atomic %, which comprises an amorphous alloy heat-treated at a temperature of from 600 to 800 K., in which sub-nanometeric precipitates generating coherent elastic strains are formed and distributed in the bcc parent phase(B2).
