Title:
TITANIUM OR TITANIUM ALLOY SHEET EXCELLENT IN BALANCE BETWEEN PRESS FORMABILITY AND STRENGTH
Document Type and Number:
Japanese Patent JP2010138459
Kind Code:
A
Abstract:
To provide a titanium or titanium alloy sheet which is excellent in a balance between press formability and strength and is useful as a material for a heat exchanger or a chemical plant.
The titanium or titanium alloy sheet is unidirectionally rolled in such a way that it has a lubricating coating applied to its surface, and the dynamic friction coefficient at the surface of the lubricating coating is controlled to <0.15. In the titanium or titanium alloy sheet, the elongation (L-El) in the rolling direction and the r value (T-r) in the direction perpendicular to the rolling direction satisfy the relation: (T-r)/(L-El)≥0.07.
