Abstract:

Nanocomposite (Nd,Dy)₂Fe₁₄B/α-Fe magnets were prepared by directly solidification (DS). The effect of wheel speed on the magnetic properties, microstructure and exchange coupling interaction has been studied. It was found that a uniform R₂Fe₁₄B/α-Fe nanocomposite structure with fine α-Fe grains can be developed at an optimum wheel speed of about 18 m/s. Without any heat treatment, the optimal ribbons (v = 18 m/s) show a strong exchange coupling interaction and good magnetic properties, e.g._iH_c=1027 kA/m, m_r =0.71, (BH)_max=174 kJ/m³.
