Abstract
A method for deoxidizing a Ti—Al alloy includes melting and holding a Ti—Al alloy containing 40 mass % or more of Al by a melting method using a water-cooled copper vessel in an atmosphere of 1.33 Pa or more, thereby decreasing an oxygen content in the Ti—Al alloy. The Ti—Al alloy is manufactured using an alloy material composed of a titanium material and an aluminum material. The alloy material contains oxygen in a total amount of 0.1 mass % or more.
