摘要： 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.

摘要： Provided is an Alnico alloy that is lean (i.e., lower) in Co content and yet at least retains substantially the same or better magnetic properties as the corresponding more costly, commercially available Alnico grade alloy with higher Co content, such as grades 8 and 9, which include 31.5 atomic % or more Co, in order to save significant material costs.

摘要： A method is provided for treating a rare earth metal-bearing scrap material by melting an extractant selected from the group consisting of bismuth (Bi) and lead (Pb) and contacting the melted extractant and the scrap material at a temperature and time to recover at least one of the light rare earth metal content and the heavy rare earth metal content as a metallic extractant alloy, which can be subjected to vacuum distillation or sublimation to recover the rare earth metal(s). The method can be practiced to recover the light rare earth metal content and the heavy rare earth metal content concurrently in a one-step process or separately and sequentially in a two-step process.

摘要： A method of treating rare earth metal-bearing permanent magnet scrap, waste or other material in a manner to recover the heavy rare earth metal content separately from the light rare earth metal content. The heavy rare earth metal content can be recovered either as a heavy rare earth metal-enriched iron based alloy or as a heavy rare earth metal based alloy.
