Abstract: METHOD AND APPARATUS OF HEAT TREATING AN INTEGRALLY BLADED ROTORA process for heat treating selected portions of an integrally bladed rotor (IBR) having a plurality of blades, the process using an IBR on a fixture having a rotor engaging portion that moves the IBR into an environmental chamber. An IR heater is placed on one of the IBR blades and heat treated after air has been removed from the chamber and an inert gas is added. The IR heater is lifted from the blade and indexed to position another blade on the IBR. The process is repeated until all the IBR blades are heat treated.Fig. 1

Abstract: WELDING Ti-6246 INTEGRALLY BLADED ROTOR AIRFOILSA method is disclosed for welding a first metal to a Ti-6246 alloy airfoil. The method consists of depositing weld metal by fusion welding and reshaping the airfoil to predetermined dimensions. A post weld heat treatment is applied to relieve residual stresses. Surface treatment such as laser shock peening introduces residual surface compressive stresses to enhance the mechanical integrity of the airfoil.Fig. 1

Abstract: An example method of attaching an airfoil for an integrally bladed rotorincludes placing a support collar in an installed position around at least a leading edge and trailing edge of an airfoil stub to be repaired in an integrally bladed rotor. The support collar and the airfoil stub together have a midline that is positioned between opposing, laterally outer surfaces of the airfoil stub when the support collar is in theinstalled position. The method performs linear friction welding to add a replacement airfoil to the airfoil stub.Figure 1

Abstract: A method is provided that involves a component (20) including a first fastener aperture (36) that extends through the component (20). During the method, the component (20) is machined to enlarge the first fastener aperture (36) to provide an enlarged aperture (54). The component (20) is friction plug welded to plug the enlarged aperture (54) with friction plug welded material (56). A second fastener aperture (36B) is machined in the friction plug welded material (56), where the second fastener aperture (36B) extends through the component (20).

Abstract: A device and method for locally heat treating at least one airfoil in an integrally bladed rotor device. A pair of IR heat sources are positioned to direct IR heat rays in the direction where local heat treatment is required. A pair of parabolic minors are positioned to direct the IR heat rays on to the metal component. The heat treating is useful after welding the airfoil on to the rotor device.Figure 1

Abstract: The present invention relates to a silver braze alloy having improved wetting properties. The silver braze alloy consists essentially of from about 52.25 wt% to about 57.0 wt% silver, from about 38.95 to about 43.0 wt% copper, from about 0.5 wt% to about 5.5 wt%, preferably from about 1.0 wt% to about 5.5 wt%, manganese, and up to about 2.5 wt%, preferably from about 1.5 wt% to about 2.5 wt%, nickel. The alloy further may contain 0.15 wt% total of other trace elements.
