Abstract
A method for making titanium alloy products comprises the steps of: PA1 superplastic-forming .alpha.+.beta.-titanium alloy at a predetermined temperature, said .alpha.+.beta.-titanium alloy consisting essentially of 3.45 to 5 wt. % Al, 2.1 to 5 wt. % V, 0.85 to 2.85 wt. % Mo, 0.85 to 3.15 wt. % Fe, 0.01 to 0.25 wt. % 0 and the balance being titanium; PA1 cooling the superplastically formed titanium alloy at a cooling rate of 0.05 to 5.degree. C./sec; and PA1 aging the cooled titanium alloy at a temperature of 400.degree. to 600.degree. C. PA1 The superplastically formed titanium alloy can be diffusion-bonded, thereafter the diffusion-bonded titanium alloy can be cooled and aged.
