Abstract
Official abstract text for this publication.
A titanium alloy includes 15 to 27 atomic % (at%) of tantalum (Ta) and 0 to 8 at% of tin (Sn), the balance being titanium (Ti) and unavoidable impurities, when the entire 5 amount of the titanium alloy is taken as 100 at%. Therefore, the titanium alloy provided has characteristics suitable for medical device materials, biocompatible materials, etc.

A method for producing a titanium alloy, the method comprising: melting a material consisting of 15 to 27 atomic % (at %) of tantalum (Ta) and 1 to 8 at % of tin (Sn) with the balance being titanium (Ti) and unavoidable impurities, when an entire amount of the titanium alloy is taken as 100 at %, wherein the titanium alloy has a Young's modulus of 40 Gpa or lower and a tensile strength of 850 MPa or larger. 12 . The method of claim 11 wherein a value obtained by dividing a total atomic % of the tantalum and the tin by a total atomic % of the titanium and the unavoidable impurities is within a range of 0.34 to 0.36 within which the titanium alloy has both at once a maximum tensile strength and a minimum Young's modulus. 13 . The method of claim 11 wherein a value obtained by dividing a total atomic % of the tantalum and the tin by a total atomic % of the titanium and the unavoidable impurities is within a range of 0.34 to 0.36 within which the titanium alloy has both at once a maximum tensile strength and a minimum Young's modulus. 14 . A method for producing a medical tool for a living body, the method comprising: melting a material consisting of 15 to 27 atomic % (at %) of tantalum (Ta) and 1 to 8 at % of tin (Sn) with the balance being titanium (Ti) and unavoidable impurities, when an entire amount of the titanium alloy is taken as 100 at % to produce a titanium alloy; and forming the titanium alloy into the medical tool by wire drawing, drawings, casting, forging and press working, wherein the titanium alloy has a Young's modulus of 40 Gpa or lower and a tensile strength of 850 MPa or larger. 15 . The method for producing a medical tool for a living body of claim 14 wherein the titanium alloy is formed into a wire having a maximum outer diameter of 0.005 mm to 1 mm.
