Abstract
Provided are a titanium-based powder excellent in fluidity and shape retention property, and an ingot and a sintered article obtained using the titanium-based powder as a material. The titanium-based powder has an average circularity of 0.815 or more and less than 0.870, a CV value of particle sizes of 22 or more and 30 or less, and an angle of repose of 29 degrees or more and 36 degrees or less.
Claims8
A titanium-based powder, which has an average circularity of 0.815 or more and less than 0.870, a coefficient of variation of particle sizes of 22 or more and 30 or less, and an angle of repose of 29 degrees or more and 36 degrees or less,
- wherein the titanium-based powder contains a spherical titanium-based powder and a non-spherical titanium-based powder,
- wherein the average circularity of primary particles of the spherical titanium-based powder is 0.85 or more and 1.0 or less, and
- wherein the average circularity of primary particles of the non-spherical titanium-based powder is 0.50 or more and less than 0.85.
