Pulse-Laser-Crystallization of Amorphous Nd3.7Pr3.4Dy0.9Fe86B5Nb1

Article Preview

Abstract:

The pulse-laser-crystallization (PLC) technique was applied to Nd3.7Pr3.4Dy0.9Fe86B5Nb1 amorphous ribbons. After irradiation with a 248nm KrF pulse excimer laser at a fequency of 15Hz for 1 min, the Nd3.7Pr3.4Dy0.9Fe86B5Nb1 amorphous ribbons crystallized into the homogeneous Nd2Fe14B/α-Fe nanocomposite permanent magnetic materials with an average grain size around 26nm. The obtained coercivity, remanence, and (BH)max values were 6.6 K, 1.23 T, and 18.5 MGOe, respectively.
