Abstract

Exchange coupled Nd₂Fe₁₄B/α-Fe nanocomposite magnets have been synthesized by melt-spun. The effect of wheel speed on the magnetic properties and microstructure has been studied. The results show that a uniform Nd₂Fe₁₄B/α-Fe nanocomposite structure with fine α-Fe grains can be obtained at an optimum wheel speed of 12 m/s. After a low temperature annealing, the magnetic properties can reach a maximum value: _iH_c = 432.2 kA/m, J_r = 1.08 T, (BH)_max = 115 kJ/m³.
