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 5-transus; the titanium base alloy consisting essentially of about 3.42 to 5 wt. % Al, 2.1 to 3.7 wt. % V, 0.85 to 3.15 wt. % Mo, at least 0.01 wt. % 0, at least one element selected from the group consisting of Fe, Ni, Co and Cr, and the balance being titanium, and satisfying the following equations: 0.85 wt. %.ltoreq.X wt %.ltoreq.3.15 wt %, 7 wt %.ltoreq.Y wt %.ltoreq.13 wt. %, X wt. %=Fe wt. %+Ni wt. %+Co wt. %+0.9.times.Cr wt. %, Y wt. %=2.times.Fe wt. %+2.times.Ni wt. %+2.times.Co wt. %+1.8.times.Cr wt. %+1.5.times.V wt. %+Mo wt. %, and hot working the heated alloy with a reduction ratio percent of at least 50%.
