Low-Cost Alloy Permanent Magnet Materials

摘要

This work focused on the preparation, structure, and properties of Fe-Nd-B permanent magnets. The rapidly expanding literature on Fe-R-B compounds and magnets was reviewed, and production of Fe14Nd2B by a reduction-diffusion process was successfully demonstrated. Supporting work at Vanderbilt University involved Mossbauer measurements on melt-spun Fe-R-B alloys and preparation of Fe-R-B by plasma-arc deposition.
