<P>PROBLEM TO BE SOLVED: To provide a superelastic titanium alloy which has both of excellent superelastic property and cold workability, is produced with adequate productivity, and does not include Ni. <P>SOLUTION: The superelastic titanium alloy for the living body comprises one or two elements of Ta and Nb which are elements for stabilizing a β phase in titanium, in such a range as to satisfy the expression: 15 mol.%≤1.5x+y≤45 mol.%, (wherein x represents a Nb content; and y represents a Ta content), further 1-20 mol.% Zr, 1-6 mol.% Mo, while controlling the total amount of Ta, Nb, Zr and Mo into 60 mol.% or less, and the balance Ti with unavoidable impurities. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
