  • Phase stable carbide reinforced nickel-base superalloy eutectics having improved high temperature stress-rupture strength and improved resistance to surface carbide formation
    Patent number: 4522664
    Abstract: Monocarbide reinforced nickel-base eutectic superalloys which are substantially phase stable and have improved high temperature stress-rupture strength with improved resistance to the formation of surface nucleated carbides are provided. These superalloys are especially suited for making unidirectionally solidified anisotropic metallic bodies in the form of vanes and rotating blades for aircraft gas turbine engines.

    Assignee: General Electric Company
    Inventors: Michael F. X. Gigliotti, Jr., Swe-Wong Yang, Melvin R. Jackson, Charles A. Bruch, Xuan Nguyen-Dinh
  • Transverse ductile fiber reinforced eutectic nickel-base superalloys
    Patent number: 4292076
    Abstract: A unidirectionally solidified anisotropic metallic composite body exhibiting improved high temperature ductility and strength properties comprising a nickel-base refractory-metal-monocarbide-reinforced eutectic superalloy containing boron.
    Type: Grant
    Filed: April 27, 1979
    Date of Patent: September 29, 1981

  • Directional solidification furnace
    Patent number: 4202400
    Abstract: A directional solidification furnace is provided in which the susceptor is characterized by at least one substantially longitudinal slot to provide interference with eddy current motion and lower the furnace temperature in the slotted region and cause the highest temperature to be near the solid-liquid interface of a casting contained therein.
    Type: Grant
    Filed: September 22, 1978
    Date of Patent: May 13, 1980
    Assignee: General Electric Company
    Inventors: Michael F. X. Gigliotti, Jr., Thomas F. Sawyer
  • Process for making ceramic molds having a metal oxide barrier for casting and directional solidification of superalloys
    Patent number: 4031945
    Abstract: At least one element of a superalloy cast into a refractory oxide-silica investment mold is oxidized to form a metal oxide barrier layer at the mold-metal interface to permit directional solidification of the cast superalloy at elevated temperatures without metal-mold reaction.
    Type: Grant
    Filed: April 7, 1976
    Date of Patent: June 28, 1977
    Assignee: General Electric Company
    Inventors: Michael F. X. Gigliotti, Jr., Charles D. Greskovich
  • Process for forming a barrier layer on ceramic molds suitable for use for high temperature eutectic superalloy casting
    Patent number: 3972367
    Abstract: A method of forming a metal oxide barrier layer at the interface between a refractory oxide-silica investment mold and a contained metal superalloy includes the firing of the mold or the mold-metal system, in a controlled prevailing atmosphere having a predetermined amount of oxygen therein. The barrier layer enables directional solidification of the contained superalloy at elevated temperatures to occur without metal-mold reaction.
