  • TURBINE ENGINE ROTOR, METHOD OF PRODUCING THE SAME, METHOD OF JOINING NI-BASED SUPERALLOY MEMBER AND STEEL MEMBER, AND JUNCTION STRUCTURE OF NI-BASED SUPERALLOY MEMBER AND STEEL MEMBER
    Publication number: 20140133986
    Abstract: A method of producing a turbine engine rotor includes: joining a first rotor disc (25H) and an intermediate member (26) together by electronic beam welding, the first rotor disc (25H) being formed of a precipitation hardened Ni-based superalloy, the intermediate member (26) being formed of a solid solution strengthened Ni-based superalloy; performing age-hardening treatment on the joined body at a first temperature which is a suitable temperature for age-hardening the precipitation hardened Ni-based superalloy; joining the intermediate member (26) and a second rotor disc (25L) together by electronic beam welding, the second rotor disc (25L) being formed of a steel; and performing annealing treatment on the joined body at a second temperature which is a suitable temperature for annealing the steel.

  • Friction stir joining apparatus
    Patent number: 7703659
    Abstract: In the friction stir joining apparatus of the present invention, a rotation control unit variably controls a rotational speed of a rotor; and a straight movement control unit controls a straight movement of the rotor so as to control a pressure applied by the rotor to the object. The tip portion of the rotating rotor is pressed against a workpiece, thus spot joining is executed. The apparatus can execute frictional stirring joining without practical trouble under simple control.
