    摘要： A method for producing an improved anisotropic magnet through an extrusion process wherein the container involved in the extrusion process is first coated, on its internal surface, with a material to prevent the bonding of the interior surface to the particle charge to be extruded and, thereby, to prevent cracking due to tensile stresses. In addition, an improved anisotropic extrusion product, with enhanced magnetic properties, can be obtained by holding the temperature of the extrusion product at temperatures between 1000null F. and 1750null F. for between 1 and 10 hours.

    摘要： A method for producing rare earth sintered magnets includes the steps of pressing and compacting an alloy powder for the rare earth sintered magnets, thereby preparing a plurality of green compacts, arranging the green compacts on a receiving plane in a direction in which a projection area of each of the green compacts onto the receiving plane is not maximized, and heating the green compacts, thereby sintering the green compacts and obtaining a plurality of sintered bodies.
