Document Type and Number:
Japanese Patent JP2001262257
Kind Code:
A
Abstract:
To produce inexpensive titanium excellent in impact resistance and to provide its producing method.
The concentrations of O, N, C and Fe are controlled to prescribed ranges without adding alloy elements such as Al, Mo and V to secure cold workability, and on the other hand, the Vickers hardness of the cross section of a titanium formed product in a state of being work-hardened in the combination of preliminary working and annealing performed before forming into a titanium formed product or in the process thereof is controlled to a prescribed range in accordance with the componential concentrations thereof, by which a titanium formed product excellent in impact resistance is obtained.
