Abstract
The invention provides a titanium alloy having improved superplastic forming characteristics and mechanical characteristics. A titanium alloy having superplastic forming characteristics consisting essentially of about 5.5 to 6.75 wt. % Al, 3.5 to 4.5 wt. % V, 0.01 to 0.2 wt. % O, 0.85 to 3.15 wt. % Fe, 0.85 to 3.25 wt. % Mo, with 2.times.Fe wt. %+Mo wt. % being from 3 to 8, and balance titanium; said alloy containing .alpha.-crystals having a grain size below about 6 .mu.m in diameter. The Fe and Mo act as .beta.-stabilizing elements and contributing elements to lowering the beta transus and to the improvement of the superplastic characteristics.
