Abstract
Titanium alloy containing iron, that is, iron-containing titanium alloy having high strength and hardness in which iron in a composition which cannot be realized in a conventional method, is contained with no segregation, and is provided in lower cost. The α+β titanium alloy or β titanium alloy is produced by a forming process such as hot extrusion of titanium alloy powder containing 3 to 15 mass % of iron powder. The method for production of the α+β titanium alloy or β titanium alloy includes a step of mixing 3 to 15 mass % of iron powder and titanium alloy powder as the remainder, and a step of performing a forming process of hot extrusion on this powder mixture.
