Abstract
An alpha-beta titanium alloy is provided. The alpha-beta titanium alloy composition includes concentrations of Al from about 4.7 wt. % to about 6.0 wt. %; V from about 6.5 wt. % to about 8.0 wt. %; Si from about 0.15 wt. % to about 0.6 wt. %; Fe up to about 0.3 wt. %; O from about 0.15 wt. % to about 0.23 wt. %; Ti and incidental impurities as a balance. The alpha-beta titanium alloy may have a solution treated and aged microstructure and an elongation of at least about 10% at room temperature. Also, the alpha-beta titanium alloy may have an Al/V ratio from about 0.65 to about 0.8, the Al/V ratio being equal to the concentration of the Al divided by the concentration of the V in weight percent.
