Patent ID: 7910052

Claim:
A near β-type titanium alloy consisting essentially of, by mass %, V: 0.5 to 1.0%, Fe: 0.5 to 2.5%, Mo: 0.5 to 2% and Cr: 3 to 5%, wherein the value of X V +2.95X Fe +1.5X Mo +1.65X Cr is from 9 to 17%, wherein X V represents the mass % of the V, X Fe represents the mass % of the Fe, X Mo represents the mass % of the Mo and X Cr represents the mass % of the Cr, and further comprising, by mass %, Al: 3 to 7%, wherein Ti and impurities constitute the residue, wherein the near β-type titanium alloy has a microstructure formed into an equiaxial structure.
