摘要： 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.

摘要： A method of manufacturing iron-based powder includes providing an iron-based molten steel manufactured through a iron making process and a steelmaking process to a tundish; and performing water atomization over the molten steel discharged through a nozzle connected to the tundish. The iron-based powder is manufactured from the molten steel refined after a molten iron tapped from a iron making process is charged into a converter without a pre-treatment process of the molten iron, thus economically providing the highly clean iron-based powder.

摘要： Systems and methods are presented for producing shot from molten material, in which two or more sprays of inert gas, such as an upper or primary spray followed by one or more lower or secondary sprays, are used to break apart large molten droplets into shot as the molten material is dropped from a crucible orifice. The upper or primary gas feed in one application acts to initially break the stream or droplets into initial droplets of a lesser size or to flatten the droplets, with the second spray then breaking up the intermediate droplets into yet smaller shot particles to be cooled and collected.

摘要： A magnetic material manufacturing method, a ribbon-shaped magnetic material manufactured by the method, a powdered magnetic material formed from the ribbon-shaped magnetic material and a bonded magnet manufactured using the powdered magnet material are disclosed. The method and the magnetic materials can provide magnets having excellent magnetic properties and reliability. A melt spinning apparatus 1 is provided with a tube 2 having a nozzle 3 at the bottom thereof, a coil 4 for heating the tube and a cooling roll 5 having a circumferential surface 53 on which dimple correcting means is provided. A melt spun ribbon 8 is formed by injecting the molten alloy 6 from the nozzle 3 so as to be collided with the circumferential surface 53 of the cooling roll 5 in an inert gas atmosphere (ambient gas) such as helium gas, so that the molten alloy 6 is cooled and then solidified. In this process, dimples to be produced on a roll contact surface of the melt spun ribbon are divided by the dimple correcting means, thereby preventing formation of huge dimples.

摘要： A method for atomizing a titanium-based material to particulates in a controlled atmosphere. In the method, titanium is skull melted in a crucible. The molten titanium-based material is transferred to a heated tundish. The molten titanium-based material may be stabilized in the heated tundish and then formed into a free-falling stream. The free-falling stream of the molten titanium-based material is impinged with an inert gas jet to atomize the molten titanium-based material. The method also includes cooling the atomized titanium-based material, and collecting the cooled atomized titanium-based material.

摘要： A method of producing a metallic powder material comprises supplying feed materials to a melting hearth, and melting the feed materials on the melting hearth with a first heat source to provide a molten material having a desired chemical composition. At least a portion of the molten material is passed from the melting hearth either directly or indirectly to an atomizing hearth, where it is heated using a second heat source. At least a portion of the molten material from the atomizing hearth is passed in a molten state to an atomizing apparatus, which forms a droplet spray from the molten material. At least a portion of the droplet spray is solidified to provide a metallic powder material.
