摘要： A titanium alloy comprising Al 4.78 to 6.44 wt.%; V 3.65 to 5.15 wt.%; Mo 1.32 to 3.58 wt.%; Cr 0.75 to 2.28 wt.%; Fe 0.00 to 0.42 wt.%; C 0.00 wt.% to 0.10 wt.%; S 0.00 wt.% to 0.10 wt.%; N up to 500 ppm; O up to 2000 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 turbine blades and stators.
