Effect of Dy Addition and Heat Treatment Conditions on the Magnetic Properties of (Nd,Dy)-Fe-B-based Sintered Magnets
Original language description
Two production methods of sintered Nd-Fe-B magnets were compared, and the effect of heat treatment (??) regimes on magnetic properties of these magnets was studied. Sintered (Nd,Dy)-Fe-? magnets with ~3 wt.% Dy were prepared using method of single alloyand method of ?mixtures? which means the mixing of powders of a basic alloy whose composition is close to the Nd2Fe14B composition and additional low-melting Dy/Co-based alloy. Two types of post-sintering HT were used. The HT1 consists in the cooling from 950 °C to the aging temperature (Tag), 5 min aging at Tag and cooling to RT. The HT2 consists in the cooling from 950 °C to RT, repeated heating up to Tag, 5 min aging and cooling to RT. It was shown that the HT regimes affect substantially the coercive force of both types of magnets. It was also found that the aging-temperature dependences Hci(Tag) corresponding to regimes of HT1 and HT2 differ markedly. An analysis of these dependences has revealed some phase microstructure transform
