Abstract AITranslate

The cause of abnormally high open-circuit flux irreversible loss (hirr) in the sintered Nd-Fe-B magnet was investigated by the means of SEM,EDAX and powder particle size analysis. The results show that non-uniform crystal grain size distribution and coarse grains in the magnet microstructure are the main factors leading to the temperature stability defects of the magnet,i, e. a small amount of the finished magnet showing abnormally high hirr The basic measure for preparing the sintered Nd-Fe-B magnet with excel- lent temperature stability is to improve the techniques of ingot casting and powder preparation, avoiding coarse powder particles,reducing very fine powder particles and ensuring uniform fine magnet microstruc- ture.
