Severe plastic deformation of Nd-Fe-B nanocomposite magnets at room temperature

A newly developed isotropic Nd2Fe14B/α-Fe nanocomposite magnet was subjected to a series of investigations of its microstructure and magnetic properties. The performance of the optimally annealed sample was found to be Hc = 9.7 kOe and σsat. = 171 emu/g. Moreover, an attempt was made to produce anisotropic nanocomposite magnets by a high-pressure torsion (HPT) experiment performed at room temperature. The microstructural analyses by TEM in 2D...
