Same Terbium, Higher Coercivity: What New Grain Boundary Diffusion Research Means for NdFeB Manufacturing
A study published this year in Applied Physics A raised the coercivity of a grain boundary diffused NdFeB magnet from 17.81 kOe to 26.47 kOe by using a terbium and copper mixed powder as the diffusion source, compared with 24.09 kOe for pure terbium hydride, under identical diffusion conditions and the same terbium dosage. Both […]
