Abstract
A titanium alloy comprising Al 3.00 to 5.50 wt. %; V 3.50 to 5.00 wt. %; Mo 1.50 to 3.00 wt. %; Cr 1.00 to 2.50 wt. %; Fe 0.00 to 0.50 wt. %; Sn 0.00 to 1.25 wt. %; Zr 0.00 to 2.00 wt. %; C 0.01 wt. % to 0.50 wt. %; Si 0.00 wt. % to 0.50 wt. %; N up to 500 ppm; O up to 2500 ppm and H up to 150 ppm; the balance being Ti and incidental elements and unavoidable impurities. Such a titanium alloy is useful for manufacturing gas turbine engine components including compressor disks, bladed disks, or casings.
