  • Single-cast, high-temperature thin wall gas turbine component
    Patent number: 5545003
    Abstract: A gas turbine component that includes a very thin wall. The gas turbine component being of a single-piece, single-cast structure. In one form of the gas turbine component it is formed of a superalloy composition and is capable of withstanding gases impinging upon the walls at temperatures greater than 4000.degree. F.

  • Moldless/coreless single crystal castings of nickel-aluminide
    Patent number: 5312584
    Abstract: Disclosed is a method of making moldless/coreless single crystal castings of NiAl(.beta.') alloys. Drops of molten NiAl(.beta.') alloy is deposited on a starter seed block of single crystal alloy and casting structures are epitaxially grown to predetermined configurations and shapes by repeatedly dropping and solidifying molten NiAl(.beta.') materials.

  • Single-cast, high-temperature, thin wall structures and methods of making the same
    Patent number: 5295530
    Abstract: Disclosed is a single-cast, thin wall structure capable of withstanding impinging gases at temperatures of 4300.degree. F. and higher, and method of making the same. Using a bleed line of the instant invention allows for a decreasing metal pressure with respect to time which prevents any damage to the thin outer mold wall.
