Abstract :

Bulk anisotropic Nanocomposite Nd₂Fe₁₄B/alpha -Fe magnets were synthesized by hot pressing and subsequent hot deforming melt-spun ribbons with addition of Zn using spark plasma sintering(SPS). With increasing of Zn contents(0-5wt%), the magnetic properties of hot pressing magnets decreased; however, the magnetic properties of hot deforming magnets increased first, and then decreased and the maximum magnetic properties obtained at 2% Zn addition: Br = 1.06T , Hcj = 805 kA/m, (BH)m=163 kJ/m³.
