Abstract
A method of making an alpha-beta titanium alloy is provided. The method includes forming a melt and solidifying the melt to form an ingot. The melt 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 at less than 1 wt. %; Fe at up to about 0.3 wt. %; 0 at less than 1 wt. %; and a balance of Ti and incidental impurities. Furthermore, the Al/V ratio in the melt is equal to the concentration of the Al divided by the concentration of the V in weight percent is from about 0.65 to about 0.8.
