    Assignee: General Electric Company
    Inventors: Irvin C. Huseby, Frederic J. Klug
  • Patent number: 4086311
    Abstract: The crushability of a ceramic article suitable for use in the casting and directional solidification of advanced superalloy materials is enhanced by utilizing a two-phase mixture of material and inducing microcracks in the material. The crushability is further enhanced by forming the article to include a predetermined porosity content.

  • Patent number: 3955933
    Abstract: A magnesium-boron composite is made by mechanically mixing magnesium powders with boron powders. An alternative embodiment includes mixing a small amount of lithium powder with the magnesium boron composite to improve the ductility. The mixed powders are processed by cold pressing, hot pressing, sintering, extruding, rolling and re-extruding.
