Abstract: Disclosed is a method of making an integrally bladed rotor. According to the method, a rotor disk comprising a radially outer rim surface is provided. A portion of the disk outer rim surface is removed, leaving a protrusion on the rotor disk outer rim surface. The disk with material removed is subjected to thermal processing. A blade comprising an airfoil and a base is positioned such that a base surface is in contact with the protrusion, and heat, pressure, and motion are applied between the blade and the disk to friction weld the base surface to the protrusion.

Abstract: A system for the x-ray topography analysis of a sample, comprising in combination, a goniometer having a base, a tube arm rotatably associated with the base, a detector arm rotatably associated with the base, and a sample stage operatively associated with the base. The system also includes an x-ray source operatively coupled with the tube arm and is capable of emitting a non-collimated beam of x-rays. A collimator is operatively associated with the x-ray source and converts the non-collimated beam of x-rays into a collimated beam of x-rays having a quasi-rectangular shape with a divergence less than three degrees in all directions. A detector operatively coupled to the detector arm.

Abstract: A method of servicing a gas turbine engine is disclosed. According to the method, a component including a titanium alloy is removed from the gas turbine engine after operating the gas turbine engine with the component in service. The removed component is subjected to heat treatment, and the heat-treated component is re-installed into the gas turbine engine or installed into a different gas turbine engine.

Abstract: Disclosed is a method of making an integrally bladed rotor. According to the method, a titanium alloy rotor disk with 15-50% by volume of primary alpha grains with a grain size less than 10 μm and secondary alpha grains comprising widmanstatten grains with a grain size less than 1.0 μm is subjected to thermal processing. After thermal processing, a blade having an airfoil and a base is positioned such that a base surface is in contact with an outer rim surface of the disk. Heat, pressure, and motion are applied between the blade and the disk to friction weld the base surface to the disk outer rim surface.
