| 英文摘要 | The coercivity of hot-deformed (Ce,Nd,Pr)-Fe-B magnet was enhanced from 1.44 T to 1.71 T by the addition of 3 wt% Pr-Cu powders for grain boundary diffusion. Microstructure analysis has shown that the formation of thick grain boundary phase with non-ferromagnetism can well isolate the adjacent main phase grains and weaken the intergranular exchange coupling, which is beneficial to coercivity enhancement. Moreover, the size of platelet shaped grains inhibited by liquid phase inside the ribbon is also one of the reasons for the increase of coercivity. In addition, the temperature stability of coercivity was improved after the diffusion of Pr-Cu alloy. |
