摘要：
The substitution of V for Zr significantly impeded the growth of grain in the Co82Zr18 ribbons during melt spinning and the amorphous Co82Zr13V5 melt-spun ribbons were successfully produced at a wheel speed of 40 m/s. The values of coercivity H-c and maximum energy product (BH)(max) first increased, reaching maximum at 560 degrees C and then they decreased sharply with increasing the annealing temperature. The optimal magnetic properties of H-c=4.0 kOe and (BH)(max)=5.0 MGOe were obtained in the amorphous ribbons annealed at 560 degrees C. A suitable grain size of Co11Zr2 phase was considered to be the main reason for the increase in coercivity. (C) 2013 Elsevier B.V. All rights reserved.
