摘要: We produced a high-quality hard magnetic Fe81Co2Nb1Nd10B6 alloy by melt spinning without additional treatment. The as-spun ribbons at wheel speed of ∼25 m/s had the best properties: remanence Br, coercive force Hc, and maximum energy product (BH)max 0.97 T, 676 kA/m, 140 kJ/m3, respectively. Nd2Fe14B/α-Fe nanocomposite phases grain sizes ∼10–30 nm. investigated how properties changed with speed, finding that they depended on structure structure, which upon over- under-quenching from melt.
