Abstract:
A method of manufacturing a titanium alloy part with a composition, in weight %, of aluminum from about 6.0 to about 6.7; vanadium from about 1.4 to about 2.0; molybdenum from about 1.4 to about 2.0; silicon from about 0.20 to about 0.35; oxygen from about 0.18 to about 0.23; iron from about 0.16 to about 0.24; carbon from about 0.02 to about 0.06; and balance titanium, is provided. The method includes a first heat treatment on an ingot of the titanium alloy, forging of the ingot to break down the cast structure, a second heat treatment on the forged ingot, rolling the forged ingot to a plate, bar or billet, and annealing the plate, bar or billet below the beta transus temperature of the titanium alloy. The first and second heat treatments are between 40 and 200° C. and between 30 and 100° C. below the beat transus temperature, respectively.

Claim (Index 1):
A method of manufacturing a titanium alloy part, comprising:\n a. performing a first heat treatment on an ingot of a titanium alloy at a temperature between 40 and 200 degrees Centigrade above the beta transus temperature of the titanium alloy, forging the ingot to break down the cast structure of the ingot, and then cooling the forged ingot, wherein the titanium alloy comprises in weight percent (wt. %): aluminum from about 6.0 to about 6.7; vanadium from about 1.4 to about 2.0; molybdenum from about 1.4 to about 2.0; silicon from about 0.20 to about 0.35; oxygen from about 0.18 to about 0.23; iron from about 0.16 to about 0.24; carbon from about 0.02 to about 0.06; and balance titanium with incidental impurities; b. performing a second heat treatment on the forged ingot at a temperature between 30 and 100 degrees Centigrade below the beta transus temperature and rolling the forged ingot to a plate, bar, or billet; and c. annealing the plate, bar or billet of the titanium alloy at a temperature below the beta transus temperature.
