Abstract: A method of increasing anisotropy of magnetic materials formed by a hydrogenation-disproportionation-desorption-recombination (HDDR) process is provided. The method includes subjecting a starting magnetic material to a hydrogenation-disproportionation (HD) step in the presence of a magnetic field to obtain intermediate materials. The strength of the applied magnetic field is between 0.25 T and 9 T, optionally less than or equal to 2 T. The HD step may be performed for a period of time between 10 and 60 minutes at a temperature of at least 600° C., optionally in the range of 600° C. to 900° C. Subsequently, the intermediate materials are subjected to a desorption-recombination (DR) step to obtain a magnetic powder. Application of the magnetic field during the hydrogenation-disproportionation step increases the magnetic anisotropy of the obtained magnetic powder. Magnetic powders obtained by the method and bonded magnets formed with the magnetic powders are also provided.

Abstract: A method for fabrication of an anisotropic magnet comprises placing magnet alloy feedstock particles in a deformable metallic container and thermomechanically working the filled container in a manner to elongate the filled container and reduce its cross-sectional area to consolidate the magnet alloy particles to an elongated shape and impart a preferential grain texture to the consolidated, elongated shape. The consolidated, elongated shape is machined to a near-final magnet shape that has a smaller dimension such as magnet length and that includes a metallic tubular skin thereon.
