    摘要: Provided are a sintered body for forming a rare-earth magnet with a high degree of orientation and high remanent magnetization, and a method for producing magnetic powder for forming the sintered body. A sintered body S that is a precursor of a rare-earth magnet, the sintered body S including crystal grains g2 of an Nd—Fe—B-based main phase with a nanocrystalline structure, and a grain boundary phase around the main phase, and the rare-earth magnet being adapted to be formed by applying hot deformation processing to the sintered body S for imparting anisotropy thereto and further diffusing an alloy for improving coercivity therein. Each crystal grain g2 that forms the sintered body S has a planar shape that is, when viewed from a direction perpendicular to an easy direction of magnetization (i.e., a c-axis direction), a rectangle having sides in the c-axis direction and sides in a direction (i.e., an a-axis direction) that is perpendicular to the c-axis direction, or a shape that is close to the rectangle.

    摘要: Dispersion strengthened aluminum base alloys are shaped into metal parts by high strain rate forging compacts or extruded billets composed thereof. The number of process steps required to produce the forged part are decreased and strength and toughness of the parts are increased. The dispersion strengthened alloy may have the formula Albal,Fea,SibXc, wherein X is at least one element selected from Mn, V, Cr, Mo, W, Nb, and Ta, “a” ranges from 2.0 to 7.5 weight-%, “b” ranges from 0.5 to 3.0 weight-%, “c” ranges from 0.05 to 3.5 weight-%, and the balance is aluminum plus incidental impurities. Alternatively, the dispersion strengthened alloy may be described by the formula Albal,Fea,SibVdXc, wherein X is at least one element selected from Mn, Mo, W, Cr, Ta, Zr, Ce, Er, Sc, Nd, Yb, and Y, “a” ranges from 2.0 to 7.5 weight-%, “b” ranges from 0.5 to 3.0 weight-%, “d” ranges from 0.05 to 3.5 weight-%, “c” ranges from 0.02 to 1.50 weight-%, and the balance is aluminum plus incidental impurities. In both cases, the ratio [Fe+X]:Si in the dispersion strengthened alloys is within the range of from about 2:1 to about 5:1.

    摘要: A method of rapidly cooling molten mixtures of alkali metal alloys in which the metal components of said alloys have a wide divergence of melting points that result in separation of the alkali metals during cool down. A calcium-sodium alloy is produced in an electrolysis cell. A method of high pressure atomization of the calcium-sodium alloy and its subsequent rapid cooling produces a calcium nodular particulate that is encased in a sodium flocculant. The material manufactured is used as a nodular electrolytic flocculant reactant in the electrolyte of an alkaline battery.

    摘要: An electrode composition for a lithium-ion battery comprising particles having an average particle size ranging from 1 μm to 50 μm. The particles include an electrochemically active phase and an electrochemically inactive phase that share a common phase boundary. The electrochemically active phase includes elemental silicon and the electrochemically inactive phase includes at least two metal elements in the form of an intermetallic compound, a solid solution, or combination thereof. Each of the phases is free of crystallites that are greater than 1000 angstroms prior to cycling. In addition, the electrochemically active phase is amorphous after the electrode has been cycled through one full charge-discharge cycle in a lithium-ion battery.
