Abstract: A bimodal metal nanocomposite of ceramic nanoparticles in a metal or metal alloy matrix has a microstructure showing a first “hard” phase containing the ceramic nanoparticles in the metal or metal alloy matrix, and a second “soft” phase comprising only the metal or metal alloy with few or no ceramic nanoparticles. The stiffness and yield strength of the bimodal metal nanocomposite is significantly increased compared to the metal or metal alloy alone, while the ductility of the metal or metal alloy is retained. A process for making the bimodal metal matrix nanocomposite includes milling a powder mixture of micrometer-size metal flakes and ceramic nanoparticles for a time sufficient to embed the ceramic nanoparticles into the metal flakes.

The reactor vessel may include a core formation region and a shell formation region downstream of the core formation region. The gaseous core precursor inlet may be upstream of the core formation region and configured to introduce gaseous core precursors to the reactor vessel. The gaseous shell precursor inlet may be downstream of the core formation region, upstream of the shell formation region, and configured to introduce gaseous shell precursors to the reactor vessel. The plasma source may be configured to produce a plasma in the core formation region and the shell formation region. The gaseous core precursors may form negatively-charged core nanoparticles in the core formation region. The gaseous shell precursors may form shells on the core nanoparticles in the shell formation region.

Abstract: Provided are: a permanent magnet wherein the magnetic field orientation process can be made simple and a degree of orientation thereof can be improved; a method for manufacturing a permanent magnet, an SPM motor using a permanent magnet, and a method for manufacturing an SPM motor. Raw material magnet is milled to magnet powder, and the magnet powder is mixed with a binder to form a compound. Then, the compound is molded by hot-melt molding to a green sheet in a shape of a sheet onto a supporting substrate. Thereafter, a magnetic field is applied to the green sheet thus molded to carry out magnetic field orientation. Further, with fixing plural green sheets after the magnetic field orientation by lamination under a deformed state thereof, the plural green sheets thus laminated are cut for shaping to a prescribed shape, which is followed by sintering to produce a permanent magnet.

Abstract: Tantalum powders produced using a tantalum fiber precursor are described. The tantalum fiber precursor is chopped or cut into short lengths having a uniform fiber thickness and favorable aspect ratio. The chopped fibers are formed into a primary powder having a controlled size and shape, narrow/tight particle size distribution, and low impurity level. The primary powder is then agglomerated into an agglomerated powder displaying suitable flowability and pressability such that pellets with good structural integrity and uniform pellet porosity are manufacturable. The pellet is sintered and anodized to a desired formation voltage. The thusly created capacitor anode has a dual morphology or dual porosity provided by a primary porosity of the individual tantalum fibers making up the primary powder and a larger secondary porosity formed between the primary powders agglomerated into the agglomerated powder.
