| Abstract: | Associated with the mass-production of sintered Nd-Fe-B magnets currently in China, an investigation is presented in this paper of the impact of compact density on microstructure and magnetic properties of sintered Nd-Fe-B magnets. Experimental results indicate that a higher compact density helps realize full densification, avoid abnormal grain growth, increase alignment degree, and therefore improve magnetic properties of sintered Nd-Fe-B magnets. |

| Keywords: | sintered Nd-Fe-B magnet compact density densification grain growth magnetic properties |
