- 摘要:
PROBLEM TO BE SOLVED: To provide a &beta type titanium alloy which achieves a low elastic modulus without using expensive Ta having a high melting point, has a mechanical strength that is equal to or higher than that of a conventional material, and has superior biocompatibility.
SOLUTION: The &beta type titanium alloy includes, by mass%, 10.5 or more but less than 25% Nb, 0.1 to 8% Sn, and one or more of 0.1 to 8% Mo, 0.1 to 6.4% Cr, 0.1 to 4.7% Mn, 0.1 to 3.2% Fe, while satisfying the expression of X=Mo+1.25Cr+1.7Mn+2.5Fe: 2 to 8 and the expression of (Nb/3.5)+X: 9 to 11, wherein the symbols of elements in the expressions represent a content (mass%) of each element. The alloy obtains an elastic modulus of 80 GPa or less.
