%X Full dense isotropic and anisotropic Nd2Fe14B/α--Fe nanocomposite magnets were prepared via sonochemistry method, spark plasma sintering (SPS) and hot deformation method. The effects of α–Fe volume fraction on the structure and magnetic properties of the magnets were investigated. For the isotropic magnets, the exchanging coupling and remanence increase as the α–Fe content increases. For the anisotropic magnets, only the magnets with no more than 2% α–Fe exhibit strong c-axis crystal texture of Nd2Fe14B phase, and the better magnetic properties are Br=1.367 T, Hci=712 kA/m, (BH)m=327 kJ/m3.
