Abstract: Methods for the production of magnetic powders, compacted magnetic bodies and sintered magnetic bodies. The methods include the use of metal carboxylate precursor compounds such as metal oxalates. The precursor compounds are heated under pressure to form metal alloy particles which can be directly formed into compacted magnetic bodies or can be further refined by using a reductant at elevated temperatures and pressures. The sintered magnetic bodies may have strong magnetic properties even if produced in the absence of a strong magnetic field.

Abstract: An internal structure of a magnetic material is phase-separated into at least a first phase and a second phase. At least one of the first phase and the second phase includes a compound having a perovskite structure. The first phase and the second phase include Mn, Sn, and N. According to this, it is possible to obtain a magnetic material in which magnetic properties such as a coercive force are improved. In addition, in a case where a rare-earth element is not included in elements that constitute the magnetic material, it is possible to obtain a magnetic material having corrosion resistance.

Abstract: An apparatus and method for manufacturing solid particles based on inert gas evaporation. The method includes forming a continuous gaseous feed flow, and injecting the continuous gaseous feed flow through an inlet into a free-space region of a reactor chamber in the form of a feed jet flow, and forming at least one continuous jet flow of a cooling fluid and injecting the at least one jet flow of cooling fluid into the reaction chamber. The feed jet flow is made by passing the feed flow at a pressure above the reactor chamber pressure in the range from 0.01·105 to 20·105 Pa through an injection nozzle. The jet flow of cooling fluid is made by passing the cooling fluid through an injection nozzle which directs the jet flow of cooling fluid such that it intersects the feed jet flow with an intersection angle between 30 and 150°.

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.
