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.
