摘要： A feedstock composition and a method of forming metal articles using powder metallurgy techniques comprise mixing metal powders and a novel aromatic binder system. The composition of the novel feedstock comprises an aromatic binder system and a metal powder. The aromatic binder system comprises an aromatic species and can further comprise lubricants, surfactants, and polymers as additives. The metal powder comprises elemental metals, metal compounds, and metal alloys, particularly for highly-reactive metals. The method of forming metal articles comprises the steps of providing and mixing the metal powder and the aromatic binder system to produce a novel feedstock. The method further comprises processing the novel feedstock into a metal article using a powder metallurgy forming technique. Metal articles formed using the present invention have an increase in carbon and oxygen contents each less than or equal to 0.2 wt % relative to the metal powder used to fabricate the article.

摘要： Nanocrystalline metal powders comprising tungsten, molybdenum, rhenium or niobium can be synthesized using a combustion reaction. Methods for synthesizing the nanocrystalline metal powders are characterized by forming a combustion synthesis solution by dissolving in water an oxidizer, a fuel, and a base-soluble, ammonium precursor of tungsten, molybdenum, rhenium, or niobium in amounts that yield a soichiometric burn when combusted. The combustion synthesis solution is then heated to a temperature sufficient to substantially remove water and to initiate a self-sustaining combustion reaction. The resulting powder can be subsequently reduced to metal form by heating in a reducing gas environment.

摘要： A method for joining together two or more ceramic and/or metal parts by providing a braze consisting of a mixture of copper oxide, silver, and ceramic particulate. The braze is placed upon the surfaces of the parts, which are then held together for sufficient time and at a sufficient temperature to cause the braze to form a bond between the parts. The addition of the ceramic particulate increases the viscosity of the braze, decreasing squeeze out, decreasing the formation of air pockets, decreases the formation of brittle phases by providing nucleation sites and increases the flexural strength of the joint.

摘要： A method for joining two ceramic parts, or a ceramic part and a metal part, and the joint formed thereby. The method provides two or more parts, a braze consisting of a mixture of copper oxide and silver, a diffusion barrier, and then heats the braze for a time and at a temperature sufficient to form the braze into a bond holding the two or more parts together. The diffusion barrier is an oxidizable metal that forms either a homogeneous component of the braze, a heterogeneous component of the braze, a separate layer bordering the braze, or combinations thereof. The oxidizable metal is selected from the group Al, Mg, Cr, Si, Ni, Co, Mn, Ti, Zr, Hf, Pt, Pd, Au, lanthanides, and combinations thereof.

摘要： Methods of aluminizing the surface of a metal substrate. The methods of the present invention do not require establishment of a vacuum or a reducing atmosphere, as is typically necessary. Accordingly, aluminization can occur in the presence of oxygen, which greatly simplifies and reduces processing costs by allowing deposition of the aluminum coating to be performed, for example, in air. Embodiments of the present invention can be characterized by applying a slurry that includes a binder and powder granules containing aluminum to the metal substrate surface. Then, in a combined step, a portion of the aluminum is diffused into the substrate and a portion of the aluminum is oxidized by heating the slurry to a temperature greater than the melting point of the aluminum in an oxygen-containing atmosphere.
