Production of Nd-Fe-B bulk nanocomposite magnets by hot deformation

In this study, the effects of Nd70Cu30 alloy powder addition on the microstructures and magnetic properties of Nd4Fe77.5B18.5 hot-deformed magnets were investigated. The Nd4Fe77.5B18.5 hot-deformed magnets consisted of the α-Fe, Fe3B, and Nd2Fe14B phases and were found to be nanocomposite. The coerc...

description In this study, the effects of Nd70Cu30 alloy powder addition on the microstructures and magnetic properties of Nd4Fe77.5B18.5 hot-deformed magnets were investigated. The Nd4Fe77.5B18.5 hot-deformed magnets consisted of the α-Fe, Fe3B, and Nd2Fe14B phases and were found to be nanocomposite. The coercivity of the Nd4Fe77.5B18.5 bulk nanocomposite magnets increased with Nd70Cu30 alloy powder addition. It was found that the Nd70Cu30 alloy reacted with the α-Fe and Fe3B phases in the Nd4Fe77.5B18.5 bulk nanocomposite magnets and formed the Nd2Fe14B phase. The Nd-Fe-B bulk nanocomposite magnet with 30% Nd70Cu30 alloy exhibited a high remanence of 9.72 kG and a high coercivity of 2.65 kOe.
