Abstract:
The effects of PrHx addition on the magnetic properties, microstructure and bending strength have been studied for the sintered Nd-Fe-B magnets. It shows that the bending strength and coercivity can be effectively improved and enhanced by the addition of PrHx for the experimental magnets. The magnets have the optimal microstructure according to SEM images, and the atoms diffusion can be potentially improved among the magnetic main phase Nd2Fel4B after the PrHx addition.
