| 英文摘要 | The coercivity of hot-deformed magnets is enhanced with slight reduction of remanence by spraying Pr70Cu30 powders on magnets' precursor melt-spun Nd-Fe-B powders. The distribution of rare earth rich phases in diffused sample is superior to original magnet. The thermal stability of the diffused magnets is comparable to the sintered sample with 1 wt% Dy content and much better than the sintered grade 42SH HRE-free sample. The reversed magnetic domains of the pre-saturated samples appear when the temperature reaches 125 degrees C in coarse grains near ribbon surface and propagated like avalanche by further increasing the temperature. The thermal stability of hot-deformed magnet can be largely optimized from the magnetic domain variation dependent on temperature enhancement. |
