Abstract: A method of making dispersion-strengthened alloy particles involves melting an alloy having a corrosion and/or oxidation resistance-imparting alloying element, a dispersoid-forming element, and a matrix metal wherein the dispersoid-forming element exhibits a greater tendency to react with a reactive species acquired from an atomizing gas than does the alloying element. The melted alloy is atomized with the atomizing gas including the reactive species to form atomized particles so that the reactive species is (a) dissolved in solid solution to a depth below the surface of atomized particles and/or (b) reacted with the dispersoid-forming element to form dispersoids in the atomized particles to a depth below the surface of said atomized particles. The atomized alloy particles are solidified as solidified alloy particles or as a solidified deposit of alloy particles. Bodies made from the dispersion strengthened alloy particles, deposit thereof, exhibit enhanced fatigue and creep resistance and reduced wear as well as enhanced corrosion and/or oxidation resistance at high temperatures by virtue of the presence of the corrosion and/or oxidation resistance imparting alloying element in solid solution in the particle alloy matrix.

Abstract: Provided are a rare-earth permanent magnet whose magnet density after sintering is very high and a method for manufacturing a rare-earth permanent magnet. Thus, a magnet raw material is milled into magnet powder, and then, a compound 12 is formed by mixing the magnet powder thus milled with a binder. Next, the compound 12 thus formed is subjected to a hot-melt molding onto a supporting substrate 13 so as to form a green sheet 14 molded to a sheet-like shape. Thereafter, while the green sheet 14 thus molded is softened by heating, magnetic field orientation is carried out by applying a magnetic field to the green sheet 14 thus heated; and further, the green sheet 14 having been subjected to the magnetic field orientation is calcined by a vacuum sintering, which is further followed by a pressure sintering to produce a permanent magnet 1.

Abstract: A powdered material preform includes a pressed powdered metal or other powdered material, where the preform is processed and sealed so that a skin or shell is formed at the outer surface of the preform (such as via melting an outer layer or surface of the preform or via adding an outer layer around the preform or via a combination thereof), with an inner portion of the preform comprising pressed powdered material. The skinned preform may comprise a shape that is generally similar to that of a final product or part to be formed, or may simply comprise a puck or shape of approximately the same mass of the shape being formed, and the skinned preform is suitable for use in subsequent densification and/or consolidation processes or combinations thereof to form the final, fully processed part.

Abstract: A gas sensor and a method of fabricating the same are provided. The gas sensor includes a substrate, carbon nanotubes (CNTs) adsorbed onto the substrate, platinum nanoparticles (NPs) decorated to surfaces of the CNTs, and an electrode formed on the substrate onto which the CNTs with the platinum NPs decorated thereto are adsorbed. When the platinum NPs and CNTs are used as a sensing material, the gas sensor can be useful in sensing gases with high sensitivity even when present at a low concentration of at least 2 ppm and stably sensing noxious gases such as C6H6, C7H8, C3H6O, CO, NO, and NH3 as well as NO2, and can have particularly excellent selectivity and response characteristics with respect to NO2 gas.
