1. A method for forming an alloy component having a beta transus temperature and a titanium silicide solvus temperature, the method comprising:
hot working a titanium alloy ingot at a temperature that is above the beta transus temperature, wherein the titanium alloy ingot comprises 6 wt % to 7 wt % aluminum; 2.5 wt % to 5.5 wt % vanadium; 0.1 wt % to 1 wt % iron; 0.1 wt % to 2 wt % molybdenum; 0.01 wt % to 0.2 wt % carbon; up to 0.3 wt % oxygen; 0.1 wt % to 2 wt % silicon; up to 2 wt % of zirconium; up to 2 wt % of tin; and a balance of titanium;
hot working the titanium alloy ingot at a temperature that is below both the beta transus temperature of the alloy and the titanium silicide solvus temperature of the alloy;
hot working the titanium alloy ingot at a temperature that is above the beta transus temperature of the alloy but below the titanium silicide solvus temperature of the alloy;
hot working the titanium alloy ingot at a temperature that is below both the beta transus temperature of the alloy and the titanium silicide solvus temperature, thereby forming a billet;
hot working the billet at a temperature below both the beta transus temperature of the alloy and the titanium silicide solvus temperature of the alloy to form a forging; and
solution heat treating the forging at a temperature below the beta transus temperature of the alloy and the titanium silicide solvus temperature of the alloy.
