Abstract: Provided are a method for producing powder for a magnet, and methods for producing a powder compact, a rare-earth-iron-based alloy material, and a rare-earth-iron-nitrogen-based alloy material. Magnetic particles constituting the powder each have a texture in which grains of a phase of a hydride of a rare-earth element are dispersed in a phase of an iron-containing material. The uniform presence of the phase of the iron-containing material in each magnetic particle results in powder having excellent formability, thereby providing a powder compact having high relative density. The powder is produced by heat-treating rare-earth-iron-based alloy powder in a hydrogen atmosphere to separate the rare-earth element and the iron-containing material and then forming a hydride of the rare-earth element. The powder is compacted. The powder compact is heat-treated in vacuum to form a rare-earth-iron-based alloy material. The rare-earth-iron-based alloy material is heat-treated in a nitrogen atmosphere to form a rare-earth-iron-nitrogen-based alloy material.

Abstract: A continuous hot bonding method for producing a bi-material strip with a strong bond therebetween is provided. The method comprises sanding a first strip formed of steel; and applying a layer of first particles, typically formed of copper, to the sanded first strip. The method next includes heating the first strip and the layer of the first particles, followed by pressing a second strip formed of an aluminum alloy onto the heated layer of the first particles. The aluminum alloy of the second strip includes tin particles, and the heat causes the second particles to liquefy and dissolve into the melted first particles. The first particles and the second particles bond together to form bond enhancing metal particles, which typically comprise bronze.

Abstract: The present invention discloses manufacturing methods of a powder for compacting rare earth magnet powder and rare earth magnet that omit jet milling process, which comprises the steps as follows: 1) casting: casting the molten alloy of rare earth magnet raw material by strip casting method to obtain a quenched alloy with average thickness in a range of 0.2˜0.4 mm; 2) hydrogen decrepitation: decrepitating the quenched alloy and a plurality of rigid balls into a rotating hydrogen decrepitation container simultaneously, the quenched alloy is crushed under a hydrogen pressure between 0.01˜1 MPa, cooling the alloy and the balls, then screening the mixture to remove the rigid balls and obtain the powder. As the jet milling process is omitted, the oxygenation during the process of the jet milling may be avoided, therefore the process may be non-oxide, and the mass production of magnet with super high property may be possible.

Abstract: A process for the removal of adsorbed water from the surface of powder materials includes the step of flowing a heated gas over the powder. The temperature of the gas is below the cracking temperature of the water. The gas is inert with the powder. An ultraviolet light is applied to the powder at a wavelength that will pass through the gas, heat the adsorbed water and desorb it, and reflect from the powder. The ultraviolet light has a wavelength between 10-185 nm. Water is removed from the powder with the flowing gas.

Abstract: An embossing method and apparatus utilizes 3D printing by digitally dispensing\ink jet printing to apply texturing features to a work roll or a sheet that may be fed into a rolling mill to emboss sheet material like aluminum alloy sheet. The printed pattern is highly variable and may be produced quickly and easily allowing low volume embossing. The printed pattern may be removed from a work roll after use to allow the roll to be reused. Alternatively, a sheet receives the printed pattern, is rolled and then the printed material removed from the resultant depression.
