    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 briquette, 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.

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

    摘要： A titanium thin sheet of 0.2 mm or less in thickness, containing: Fe of 0.1 mass % or less and O (oxygen) of 0.1 mass % or less in a bulk, wherein a sheet thickness (mm)/a grain size (mm) ≧3, and the grain size ≧2.5 μm are satisfied, and a hardened layer is included at a surface, and a region of the hardened layer is a depth of 200 nm or more and 2 μm or less from the surface. The titanium thin sheet is supplied with excellent workability and high surface hardness, and is able to be suitably used for various purposes such as, for example, acoustic components (a speaker vibration plate and so on).

    摘要翻译： 厚度为0.2mm以下的钛薄片，其主要成分为：Fe为0.1质量％以下，O（氧）为0.1质量％以下，其中板厚（mm）/粒径（mm） ≥3，粒径≥2.5μm，表面含有硬化层，硬化层的表面的深度为200nm以上2μm以下。 钛薄片具有优异的可加工性和高表面硬度，并且能够适用于各种目的，例如声学部件（扬声器振动板等）。
