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
