| 英文摘要 | In this work, the effects of rare earth(RE) elements distribution on the magnetic properties and the microstructure of the (PrNd)-(Y10-xCex)-Fe-B sintered magnets have been studied. A remarkable increase has been achieved in coercivity from 8.85 kOe to 10.39 kOe for x = 2. Microstructure studies show that the recognizable core-shell distribution characteristics are maintained in the matrix phase with x increasing. In addition, high abundance rare earths(HARE) content in the matrix phase is restrained because of amount of Ce-rich intergranular phase forming in the triple junction areas. Combining the merit of the core-shell distribution of Y and reduced HARE content in 2:14:1 phase, a higher magnetocrystalline anisotropy field is obtained. The formation of Ce-rich intergranular phase is also beneficial for the (PrNd)-(YCe)-Fe-B sintered magnets to maintain high Curie temperature. This work suggests that Y-Ce co-substitution can tune the distribution of HARE elements to effectively improve the magnetic properties of the (PrNd)-(YCe)-Fe-B sintered magnets and promote the efficient utilization of RE elements. |
