    摘要： A method is taught for joining a wrought alloy material to a cast alloy, so as to obtain a joint having superior structural integrity. A cast nickel-base superalloy part may be bonded to a wrought nickel-base superalloy part, for example, by positioning a suitable part or blank of said wrought superalloy adjacent to the cast superalloy part, applying a local bonding force to the interface while locally heating the interface to a temperature which causes localized softening, metal flow, and bonding, removing said bonding force, and subjecting the bonded assembly to a local or isothermal heat treatment so as to minimize distortion, optimize properties, and stress relieve the bonded assembly. This method may be used, for example, for the repair or replacement of vane assembly retaining lugs, whereby a replacement lug of a wrought alloy is solid state bonded to the vane assembly in place of the previous retaining lug.

    摘要： A method for replacing a rotor blade on an integrally bladed rotor having a disk is provided, comprising the steps of: (a) removing a damaged rotor blade, leaving a stub portion of the rotor blade extending out from the disk, the stub portion of the rotor blade having a suction side and a pressure side; (b) providing a die, having a pressure side and a suction side, wherein each side includes a platform trough; (c) fastening the die to the rotor blade stub, with the pressure side of the die positioned on the pressure side of the stub, and the suction side of the die positioned on the suction side of the stub; (d) extruding a portion of the rotor blade stub into the platform troughs, thereby creating a platform; and (e) attaching a rotor blade to the platform.
