ABSTRACT:
A method of making a titanium base alloy comprising the steps of heating a titanium base alloy to a temperature ranging from .beta.-transus minus 250.degree. C. to .beta.-transus; and hot working the heated alloy with a reduction ratio of at least 50%. The titanium base alloy consists essentially of about 3.42 to 5 wt. % Al, 2.1 to 3.7 wt. % V, 0.85 to 2.37 wt. % Mo, at least 0.01 wt. % O, at least one element selected from the group consisting of Fe, Co, Cr, and the balance being titanium. The invention also includes superplastic forming of said alloys. The titanium alloy satisfies the following equations:
