    摘要: Uber-cooled multi-alloy integrally bladed rotors (IBR) are made having blades with internal cooling passages with a cavity in the root portion attached to a disk having a protrusion on the periphery of the disk. The blades are put on the protrusion and the blade and disk are forced together, followed by locally heating the blade cavity/disk protrusion to a temperature between the blade and disk material softening temperatures, causing the protrusion to deform against the blade cavity, and holding them in place until bonding occurs. Subsequent to bonding the portion of the blade that defines the cavity is removed.

    摘要: Fabrication methods are described for producing an integrally bladed rotor wherein single crystal blade portions are securely metallurgically bonded to a polycrystalline disk. The polycrystalline disk is fabricated with protruding portions in the location where the blades are to be bonded. The blades are fabricated with a root portion having a cavity adapted to mate with the disk protrusions. The blade and disk are assembled and forced. Localized heating causes localized softening metal flow in the disk protrusion. Bonding occurs as a result of this combination of softening and force.
