Titanium material

Abstract

An object of the present invention is to provide a titanium plate having high strength and excellent workability. In order to achieve this object, the present invention provides a titanium material having an iron content of 0.60% by mass or less and an oxygen content of 0.15% by mass or less, with the balance being titanium and unavoidable impurities, the titanium material having a worked structure formed by working accompanied by plastic deformation and a recrystallized structure formed by annealing after the working, wherein the titanium material is formed such that the average particle size of crystal grains of the recrystallized structure is 1 μm or more and 5 μm or less, and the area of a non-recrystallized part in the cross-sectional area of the titanium material is more than 0% and 30% or less.

1 . A titanium material having an iron content of 0.60% by mass or less and an oxygen content of 0.15% by mass or less, with the balance being titanium and unavoidable impurities,
