    Abstract: A method of manufacturing a sintered body includes a first process of forming a metal powder containing carbon into a compact having a predetermined shape and a second process of baking the compact in a hermetically sealed space so as to produce a sintered body. The hermetically sealed space has an atmosphere having a pressure of 60 kPa to 140 kPa and contains a hydrogen gas and an oxygen gas. The sum of partial pressures of the hydrogen gas and the oxygen gas is not more than 3 Pa.

    Abstract: Glycerol is used as a solvent medium for the precipitation of a complex of nickel and glycerol material. The precipitate is separated from the liquid solvent and dried and calcined in air to produce small (nanometer size) particles characterized by a nickel core encased in a nickel oxide shell. The proportions of nickel core and nickel oxide shell can be controlled by management of the time and temperature of heating in air. Prolonged heating in air can produce nickel oxide particles, or calcining of the precipitate in nitrogen produces nickel particles.

    Abstract: A magnetic powder is provided composed of particles that, even when the particle size is refined, exhibits excellent magnetic properties, in particular, a high coercive force, for use in a high-density recording medium. The invention also provides a magnetic recording medium using the powder. The powder is an iron system magnetic powder containing, as an atomic ratio of Fe, a total of 0.01 to 10 at. % of one or more selected from W and Mo, particularly a magnetic powder comprised mainly of Fe16N2. The magnetic powder is able to exhibit a high coercive force of 238 kA/m (3000 Oe) or more. In addition to the W and Mo, the magnetic powder may contain, as an atomic ratio of Fe, a total of up to 25 at. % of one or more selected from Al and a rare earth element (defined as including Y).

    Abstract: A die comprises metal-rich sections which form an inner wall and an outer wall of the die, respectively. Gradient sections are disposed adjacent to the metal-rich sections, respectively. Further, a ceramics-rich section is disposed between the gradient sections. A punch comprises an inner ceramics-rich section, a gradient section, and an outer metal-rich section. In the die, the composition ratio of metal gradually decreases from the metal-rich sections to the ceramics-rich section. Similarly, in the punch, the composition ratio of the metal gradually decreases from the metal-rich section to the ceramics-rich section.

    Abstract: The present invention provides metal powder compositions for pressed powder metallurgy and methods of forming metal parts using the metal powder compositions. In one embodiment, the metal powder composition according to the invention includes a blend of primary metal particles, one or more liquid phase forming materials or precursors thereof, a lubricant and an organic acid that is capable of reacting with an oxide of a metal in the primary metal particles to form an organic metal salt that decomposes when the metal powder composition is sintered under reducing or non-oxidizing conditions. During a “delubing” step, the organic acid reacts with an oxide of a metal in the primary metal particles to form an organic metal salt that decomposes into a base metal or a metal-carbide during sintering.
