Microstructure and Magnetic Properties of Nd8.5Fe77.1B6.4Co4Zr3Nb0.5V0.5 Ribbons

摘要：

Microstructure and magnetic properties of Nd<,8.5>Fe <,77.1>B<,6.4>Co<,4>Zr<,3>Nb<,0.5>V<,0.5> nanocomposite ribbons were investigated. A fine and uniform grain with 30nm in average size was achieved for the ribbons annealed at 710℃ for 4 min, which enhanced the interaction coupling between grains and improved the magnetic properties. The results of three-dimensional atom probe (3DAP) revealed that V- enriched intergranular phase existed at the grain boundaries, suppressing the grain growth during crystallization process. The remanence and coercivity for annealed ribbons reached to 80emu·g<-1> and 567kA·m <-1>, respectively.
