Effect of Al-Zn alloy wafer grain boundary diffusion on the magnetism and microstructure of sintered NdFeB magnets

Xi Liu, Wenxi Fang, Ken Perlin

This study systematically investigates Al-Zn grain boundary diffusion (GBD) treatment on sintered Nd-Fe-B magnets using $A{l}_{80}Z{n}_{20}$ alloy sheets as the diffusion source. The a…
