<p>A titanium alloy having high elastic deformation capacity, characterized in that it consists substantially of a Va Group element and titanium and has a tensile strength at elastic limit of 950 Mpa or more and an elastic deformation capacity of 1.6 % or more; and a method for producing the titanium alloy which comprises a cold working step of applying a cold working of 10 % or more to a raw material for a titanium alloy consisting substantially of a Va Group element and titanium and an aging treatment step of subjecting the resultant cold-worked material to an aging treatment under conditions wherein a temperature is 150 to 600 °C and a Larson-Miller parameter (P) is 8.0 to 18.5. The titanium alloy exhibits a high elastic deformation capacity and a high tensile strength at elastic limit and thus can be used for various products in a wide range of applications.</p> |
