In recent years, a method for preparing fully dense bulk nanocomposite rare-earth magnets from directly devitrification of Nd-Fe-B based bulk metallic glasses has been developed. Since the method has become a research hotspot, a lot of efficient works on glass-forming ability and hard magnetic properties have been done. Some research results are introduced in this paper. It is revealed that microstructure control including composition and distribution of soft and hard magnetic phases is the key of obtaining excellent performance of bulk nanocomposite permanent magnet.
