This paper deals with the effect of annealing on the magnetism of the sintered NdFeB magnet with a composi- tion of Nd3oB5M Alo.6Nbo.7Feft2.4- Microstructural investigations of the grain size and grain boundaries with SEM were carried out. Microstructural investigations showed the presence of some Nd-rich phase in grain boundaries and main phase. The results of magnetic properties analysis shows that this non-magnetic Nd-rich phase, produced in annealing process, can increase or decrease the… CONTINUE READING
