Abstract: The general hot deformation process consists of two steps. hot pressing and die-upsetting in order to obtain the anisotropic NdFeB magnet. This is the first report that the high anisotropy NdFeB magnets can be fabricated by single stroke hot deforming the isotropic magnet. The magnetic properties of those materials are: coercivity H-i(c) similar to 11 kOe, remanence B-r similar to 12 kG, and the maximum energy product (BH)(max) similar to 28 MG . Oe.
