FABRICATION OF DUAL ALLOY INTEGRALLY BLADED ROTORS |
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. |
