Abstract: A part formed using an metal additive manufacturing process such as a turbine airfoil with an oversized feature such as an oversized hole, where the oversized hole is filled with a preform having a shape of a normal sized hole and secured within the part using a braze or weld material, and where the preform is removed to leave within the part the normal sized hole. The preform is made of a refractory material that can be removed from the part by exposure to oxygen.

Abstract: A method for gas atomization of a titanium alloy, nickel alloy, or other alumina (Al2O3)-forming alloy wherein the atomized particles are exposed as they solidify and cool in a very short time to multiple gaseous reactive agents for the in-situ formation of a passivation reaction film on the atomized particles wherein the reaction film retains a precursor halogen alloying element that is subsequently introduced into a microstructure formed by subsequent thermally processing of the atomized particles to improve oxidation resistance.

Abstract: There is a problem that when a silver powder sintering paste that is substantially free from resin is used, an organic solvent used as a dispersion medium bleeds, which results in contamination and wire bonding defects. In order to solve the problem, provided is a metal powder sintering paste that contains, as a principal component, silver particles having an average particle diameter (a median diameter) of 0.3 μm to 5 μm and further contains an anionic surfactant but is substantially free from resin.

Abstract: Frangible firearm projectiles, firearm cartridges containing the same, and methods for forming the same. The firearm projectiles are formed from a compacted mixture of metal powders that includes zinc and iron powders and which may include an anti-sparking agent. The compacted mixture is heat treated for a time sufficient to form a plurality of discrete alloy domains within the compacted mixture. The frangible firearm projectile may be formed by a mechanism that includes vapor-phase diffusion bonding and oxidation of the metal powders and that does not include forming a liquid phase of any of the metal powders or utilizing a polymeric binder. A majority component of the frangible firearm projectile may be iron. One or more of zinc, bismuth, tin, copper, nickel, tungsten, boron, and/or alloys thereof may form a minority component of the frangible firearm projectile. The anti-sparking agent may include a borate, such as boric acid.

Abstract: Methods of forming dispersoid hardened metallic materials are provided. In an exemplary embodiment, a method of producing dispersoid hardened metallic materials includes forming a starting composition with a base metal component and a dispersoid forming component. The starting composition includes the base metal component in an amount from about 50 to about 99.999 weight percent and the dispersoid forming component in an amount from about 0.001 to about 1 weight percent, based on the total weight of the starting composition. A starting powder is formed from the starting composition, and the starting powder is fluidized with a fluidizing gas for a period of time sufficient to oxidize the dispersoid forming component to form the dispersoid hardened metallic material. The dispersoid forming component is oxidized while the starting powder is a solid.

Abstract: To provide a method for firing a copper paste, which improves sinterability of copper particles for the purpose of forming a copper wiring line that is decreased in the electrical conductivity. A method for firing a copper paste, which comprises: an application step wherein a copper paste is applied over a substrate; a first heating step wherein the substrate is heated in a nitrogen gas atmosphere containing from 500 ppm to 2,000 ppm (inclusive) of an oxidizing gas in terms of volume ratio after the application step, thereby oxidizing and sintering copper particles in the copper paste; and a second heating step wherein the substrate is heated in a nitrogen gas atmosphere containing 1% or more of a reducing gas in terms of volume ratio after the first heating step, thereby reducing the oxidized and sintered copper oxide.
