Enhancing the grain boundary diffusion efficiency of Tb for Nd-Fe-B magnets using dual-alloy diffusion source
Grain boundary diffusion is an effective approach to enhance coercivity for Nd-Fe-B magnets with reduced consumption of heavy rare earths (HRE). However, during diffusion treatment, the HRE tends to accumulate at the magnet surface, leading to an insufficient coercivity improvement and a decreased m...
