To study the process of annealing to achieve how the processes of annealing affect the magnetic capability

after using three different annealing process in magnets of Nd\-9Fe\-\{85\}B\-6

the different magnetic capability of nanocrystalline composite magnets have been manufactured. The magnetic capabilities have been tested. The tested results indicate that the difference of the annealing temperature and time will make the difference of the magnetic capability. The process of annealing temperature being at about 780 ℃ and the process of annealing time sustaining about 6 min will obtain high quality nanocrystalline composite magnets.
