Title:
TITANIUM ALLOY ROD MATERIAL AND METHOD FOR PRODUCING THE SAME
Document Type and Number:
Japanese Patent JP2021167449
Kind Code:
A
Abstract:
To provide a titanium alloy rod material that has excellent Dwell fatigue characteristics and has small anisotropy in the Dwell fatigue characteristics and a method for producing the same.SOLUTION: A titanium alloy rod material is composed of an α+β type titanium alloy. When the aggregate of α grains with c-axis orientation differences between adjacent α grains of 20° or less is determined as a microtexture, the microtexture has a maximum circle equivalent diameter of more than 100 μm to 1000 μm or less.SELECTED DRAWING: None
