    Abstract: A BLISK having a damaged blade, with a repair region that has a thickness less than a specified thickness as a result of damage during manufacture or prior service, is repaired by depositing repair metal onto the repair region to increase its thickness to greater than its specified thickness dimension. Only the repair region is stress relieved by heating the repair region to a stress-relieving temperature of from about 1150° F. to about 1250° F. for a time of at least about 1 hour. The intentional manipulation of microstructure in only the thinner airfoil sections allows multiple repairs, which are not possible in the thicker sections of the BLISK. An alpha-case thickness of repair metal, preferably of at least about 0.0002 inches of repair metal, is removed from a surface of the repair region.

    Abstract: A titanium-alloy article is produced by providing a workpiece of an alpha-beta titanium alloy having a beta-transus temperature, and thereafter mechanically working the workpiece at a mechanical-working temperature above the beta-transus temperature. The mechanically worked workpiece is solution heat treated at a solution-heat-treatment temperature of from about 175° F. below the beta-transus temperature to about 25° F. below the beta-transus temperature, quenched, overage heat treated at an overage-heat-treatment temperature of from about 400° F. below the beta-transus temperature to about 275° F. below the beta-transus temperature, and cooled from the overage-heat-treatment temperature.

    Abstract: A Ti-6Al-4V-0.2O (Ti64) forged article is fabricated by forging a workpiece to make a forged gas turbine engine component having a thick portion thereof with a section thickness greater than 2¼ inches. The forged article is heat treated by solution heat treating at a temperature of from about 50° F. to about 75° F. below the beta-transus temperature of the alloy, thereafter water quenching the gas turbine engine component to room temperature, and thereafter aging the gas turbine engine component at a temperature of from about 900° F. to about 1000° F. The resulting machined gas turbine engine component has a 0.2 percent yield strength of from about 120 ksi to about 140 ksi at its centerline, and a 0.2 percent yield strength of from about 160 ksi to about 175 ksi at a location about ½ inch below a surface thereof.

    Abstract: A process for detecting an aluminum-based material deposited onto a titanium-based gas turbine engine component during engine operation is disclosed. The process comprises immersing at least a portion of the titanium-based component, which has been subjected to engine operation, into an acid solution to form an etched component. The acid solution comprises sodium fluoride, sulphuric acid and water. The etched component may then be removed from the solution and visually inspected for dark areas in contrast to light areas, the dark areas indicating deposited aluminum-based material.
