Abstract:Hot-pressed and hot-deformed NdFeB with nanoscale microstructure is easy to form, with short technological process and high environmental stability. However, its coercivity didn’t achieve the ideal value, which is related to the uneven microstructure and unclear coercivity mechanism. The study of coercivity mechanism and anisotropy formation mechanism of hot-pressed and hot-deformed NdFeB is helpful to deepen the understanding of the microstructure of magnets and further improve the magnetic properties. Dual-phase nanocomposite magnets can effectively optimize the microstructure of hot-pressed hot-deformation NdFeB and improve the coercivity. The research in recent years provides a new idea and reference for the development of hot pressing and hot deformation technology.
