  • Additive manufacturing with in-situ magnetic field source
    Patent number: 12070798
    Abstract: Embodiments of the present invention provide an electromagnet alignment system for AM or 3D printing technology providing improved in-situ alignment of the magnetic particulate material as it is dispensed during deposition to form a 3D shape. In-situ alignment of the magnetic particulate material can be controlled to be unidirectional or multi-directional.

  • NEAR NET SHAPE FABRICATION OF ANISOTROPIC MAGNEST USING HOT ROLL METHOD
    Publication number: 20230405673
    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.
