Document Type and Number:
Japanese Patent JP7024861
Kind Code:
B2
Abstract:
A titanium alloy wire rod including an α phase and a β phase, the metallographic structure in an outer circumferential region extending from the surface toward the center of gravity to a depth of 3% of the wire diameter being an isometric structure having α crystal grains in which the average crystal grain size thereof is 10.0 µm or less in a cross section perpendicular to the longitudinal direction, and the metallographic structure in an internal region including the center of gravity and extending to a position at 20% of the wire diameter from the center of gravity to the surface being an acicular structure in a cross section perpendicular to the longitudinal direction.
