  • Publication number: 20040120841
    Abstract: A method of preparing an article made of a metallic material having its constituent elements includes the steps of furnishing at least one nonmetallic precursor compound, wherein all of the nonmetallic precursor compounds collectively include the constituent elements of the metallic material in their respective constituent-element proportions, and thereafter utilizing the nonmetallic precursor compound to produce a metallic injection molded brown article. The nonmetallic precursor compounds may be processed into the metallic material by first chemically reducing them to the metallic material, and then injection molding the metallic material, or first injection molding the nonmetallic precursor compounds and then chemically reducing them to the metallic material.

  • Patent number: 6737017
    Abstract: An article of a base metal alloyed with an alloying element is prepared by mixing a chemically reducible nonmetallic base-metal precursor compound of a base metal and a chemically reducible nonmetallic alloying-element precursor compound of an alloying element to form a compound mixture. The alloying element is preferably thermophysically melt incompatible with the base metal. The method further includes chemically reducing the compound mixture to a metallic alloy, without melting the metallic alloy, and thereafter consolidating the metallic alloy to produce a consolidated metallic article, without melting the metallic alloy and without melting the consolidated metallic article.

  • Publication number: 20040016319
    Abstract: 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.

  • Publication number: 20030230170
    Abstract: A metallic article made of metallic constituent elements is fabricated from a mixture of nonmetallic precursor compounds of the metallic constituent elements. The mixture of nonmetallic precursor compounds is chemically reduced to produce an initial metallic material, without melting the initial metallic material. The initial metallic material is consolidated to produce a consolidated metallic article, without melting the initial metallic material and without melting the consolidated metallic article.
