Claim 0:
1. A component of an aircraft comprising a titanium alloy, the titanium alloy comprising:
5.5 to 6.5 wt % aluminum;
3.0 to 4.5 wt % vanadium;
1.0 to 2.0 wt % molybdenum;
0.3 to 1.5 wt % iron;
0.3 to 0.7 wt % chromium;
0.05 to 0.5 wt % zirconium;
0.2 to 0.3 wt % oxygen;
maximum of 0.05 wt % nitrogen;
maximum of 0.08 wt % carbon;
maximum of 0.25 wt % silicon; and
balance titanium,
wherein a value of an aluminum structural equivalent [Al]eq ranges from 7.5 to 9.5 wt %, and is defined by the following equation:

[Al]eq=[Al]+[O]×10+[Zr]/6,

wherein a value of a molybdenum structural equivalent [Mo]eq ranges from 6.0 to 8.5 wt %, and is defined by the following equation:

[Mo]eq=[Mo]+[V]/1.5+[Cr]×1.25+[Fe]×2.5, and

wherein the component has a microstructure formed by additive manufacturing.
