Magnetic Properties of Nd8Fe83Co3B6 Nanocomposite Magnets
The influence of quenching technology, annealing temperature and time on the structures and magnetic properties of Nd8Fe83Co3B6 nanocomposite magnets was investigated. The results show that the α-Fe/Nd2Fe14B nanocomposite magnet containing a small amount of B is difficult to form amorphous state. Th...

| Zusammenfassung: | The influence of quenching technology, annealing temperature and time on the structures and
magnetic properties of Nd8Fe83Co3B6 nanocomposite magnets was investigated. The results
show that the α-Fe/Nd2Fe14B nanocomposite magnet containing a small amount of B is difficult
to form amorphous state. The magnetic properties of 26 m/s quenched Nd8Fe83Co3B6 powders
annealed at 640℃×480 s reach iHc＝513 kA/m, Br＝1.05 T and (BH)max＝92.0 kJ/m3. The
grain size is Dα-Fe＝21.5 nm and DNd2Fe14B＝30.2 nm. |
