Effect of Nd content on the microstructure and coercivity of hot-deformed Nd–Fe–B permanent magnets

The microstructure of hot-deformed Nd–Fe–B permanent magnets with different Nd contents was investigated in order to correlate them with the hard magnetic properties. A thick distinct Nd-rich grain boundary (GB) layer was observed in a high Nd content sample by scanning electron microscopy and trans...
