Publication number: 20100258260Abstract: A metallic article is produced by furnishing one or more nonmetallic precursor compound comprising the metallic constituent element(s), and chemically reducing the nonmetallic precursor compound(s) to produce an initial metallic particle, preferably having a size of no greater than about 0.070 inch, without melting the initial metallic particle. The initial metallic particle is thereafter melted and solidified to produce the metallic article. By this approach, the incidence of chemical defects in the metal article is minimized. The melted-and-solidified metal may be used in the as-cast form, or it may be converted to billet and further worked to the final form.Type: ApplicationFiled: June 28, 2010Publication date: October 14, 2010Applicant: GENERAL ELECTRIC COMPANYInventors: Andrew Philip Woodfield, Clifford Earl Shamblen, Eric Allen Ott

Patent number: 7537725Abstract: A compositionally graded gas turbine disk is made by placing a cylindrically symmetric slip case concentrically into an interior of a cylindrically symmetric outer container. A first nickel-base superalloy powder is loaded into a radially inner first portion of the interior and a second nickel-base superalloy powder is loaded into a radially outer second portion of the interior. The slip case is removed so that the first nickel-base superalloy powder and the second nickel-base superalloy powder contact in the transition region and form a non-compacted powder mass. The non-compacted powder mass is processed into a gas turbine disk, typically by compacting the non-compacted powder mass to form a compacted powder mass, and thereafter heat treating the compacted powder mass.Type: GrantFiled: September 19, 2005Date of Patent: May 26, 2009Assignee: General Electric CompanyInventors: Jon Raymond Groh, Eric Allen Ott, Robert Edward Schafrik, Daniel Donald Krueger

Patent number: 7144441Abstract: A method for forming a dispersion-strengthened material containing nanoparticles that are uniformly dispersed in a matrix phase. The method includes adding nanoparticles and a molten material to a container to form a pool within the container and rotating the container to create a convection vortex in the pool. The convection vortex is sufficient to cause the nanoparticles to be incorporated into the molten material so as to yield a molten composite material, and further causes the molten composite material to be ejected from the container. The molten composite material is then cooled to form a solid composite body comprising a uniform dispersion of the nanoparticles.Type: GrantFiled: July 3, 2003Date of Patent: December 5, 2006Assignee: General Electric CompanyInventors: Shyh-Chin Huang, Pazhayannur Ramanathan Subramanian, Robert John Zabala, Roger John Petterson, Eric Allen Ott, Srinivasa Range Gowda
