    摘要: A titanium alloy sheet having a surface roughness satisfying the relationship Ra≦2 &mgr;m in all directions and a surface waviness satisfying the relationship WCA≦10 &mgr;m shows excellent workability because of the small anisotropy with respect to mechanical properties such as bending properties, and also excellent appearance after it is formed into a component. Such surface conditions of titanium alloy sheet can be obtained by acid pickling or grinding and acid pickling after rolling. Pack rolling, especially in which a titanium alloy slab is packed with carbon steels in vacuum by electron beam welding method and then rolled, is preferable. Application of cross rolling to the rolling makes it possible to obtain smaller anisotropy with respect to mechanical properties.

    摘要: A method for making titanium alloy products comprises the steps of: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;cooling the superplastically formed titanium alloy at a cooling rate of 0.05 to 5.degree. C./sec; andaging the cooled titanium alloy at a temperature of 400.degree. to 600.degree. C.The superplastically formed titanium alloy can be diffusion-bonded, thereafter the diffusion-bonded titanium alloy can be cooled and aged.
