摘要： A titanium product 1 includes an inner layer portion 3 and a surface layer portion 2 that is joined to the inner layer portion 3. A chemical composition of the surface layer portion 2 consists of, by mass%, O: 0.4% or less, Fe: 0.5% or less, Cl: 0.020% or less, and the balance: Ti and impurities. A chemical composition of the inner layer portion 3 consists of, by mass%, O: 0.4% or less, Fe: 0.5% or less, Cl: more than 0.020% and 0.60%, and the balance: Ti and impurities. The inner layer portion 3 has pores. The area fraction of the pores in the inner layer portion 3 in a cross-section perpendicular to the longitudinal direction of the titanium product 1 is more than 0% and not more than 30%. The Cl content (Cl I ) of the inner layer portion 3, a thickness (ts) of the surface layer portion 2, and a thickness (t I ) of the inner layer portion 3 satisfy the expression [Cl I ≤ 0.03 + 0.02 × ts/ti].

摘要： A titanium-containing structure made of a titanium material includes: a package made of a commercially pure titanium material; and a filler packed into the package, wherein an internal pressure of the package is 10 Pa or less, the pressure being an absolute pressure, and wherein the filler includes at least one selected from titanium sponge, titanium briquet, and titanium scrap, and the filler has the same type of a chemical composition of the commercially pure titanium material. This titanium-containing structure enables production of a titanium product by performing hot working and eliminating the conventional melting step and forging step.
