Abstract
Provided are Ce/Co/Cu permanent magnet alloys containing certain refractory metals, such as Ta and/or Hf, and optionally Fe which represent economically more favorable alternative to Sm-based magnets with respect to both material and processing costs and which retain and/or improve magnetic characteristics useful for GAP MAGNET applications.
Claims9
A heat treated permanent magnet, comprising an alloy comprised of Ce, Co, Cu, and a refractory metal and having a heat treated bimodal microstructure with refractory metal-containing laminas precipitated and dispersed within a single grain matrix or within individual grains of a multi-grain matrix wherein the heat treated microstructure imparts magnetic properties for use as a GAP magnet.
