摘要：

The phases, microstructure, and magnetic properties of Co80Zr18-xNbxB2 (x=1, 2, 3, and 4) melt-spun ribbons were investigated. The small substitution of Nb for Zr in the Co-Zr-B melt-spun ribbons resulted in the improvement of magnetic properties, especially the coercivity. The main effect of added Nb on the coercovity of Co-Zr-Nb-B melt-spun ribbons, originated from modification of the grain size of Co11Zr2 phase. The coercivity of the Co-Zr-Nb-B melt-spun ribbons depends on the annealing temperature. The optimal magnetic properties of H-c=5.1 kOe, and (BH)(max)=3.4 MGOe were obtained in the Co80Zr15Nb3B2 melt-spun ribbons annealed at 600 degrees C for 3 min. (C) 2012 Elsevier B.V.
