Cu additions to Nd-Fe-B alloys to reduce oxygen content in the ingot and rapidly solidified ribbon |
摘要 |
A process is disclosed for producing rare earth-iron-boron alloys and magnets with reduced oxygen content and improved yield. Such a reduction in oxygen content and improvement in yield are achieved by including copper in a melt having a composition comprising a rare earth, boron, and iron, and subsequently solidifying the melt.
