Synergistic regulation and optimization of microstructure, coercivity, and thermal stability in sintered NdFeB magnets through grain boundary diffusion of Dy and Al elements
The grain boundary diffusion process (GBDP) is a well-established method for producing high-performance NdFeB magnets. However, the limited diffusion ability of heavy rare earth (HRE) elements, which are only attached to the surface of the magnet, has been a major concern in the industry. In this st...
