PURPOSE:To obtain a functional alloy having a shape memory function, excellent in mechanical strength and corrosion resistance and having good compatibility with organisms by holding the temp. of an alloy having a specified compsn. in which a part of Pd in a Ti-Pd alloy is substituted by Co to a prescribed one the thereafter rapidly cooling this alloy. CONSTITUTION:The temp. of alloy constituted of, by mol, 45 to 60% Ti and 40 to 55% Pd+Co (where <=30% Co is regulated) is held to 500 to 1000 deg.C, and this alloy is thereafter rapidly cooled. In this way, the functional alloy showing a shape memory function at a relatively low transformation temp. and excellent in workability can be obtd. Thus, this alloy is suitable for implants, artificial coxae, skeleton-straightening wires or the like. |
