摘要：
The Nd2Fe14B/alpha-Fe nanocomposite magnets multi-alloyed with Co, Nb, Zr and V were prepared by melt spinning. The grains with an average grain diameter of 20-30 nm in size shows extremely homogenous and regular characteristic. The remanence and coercivity reach to 80emu/g and 567kA/m, respectively for the ribbons annealed at 710 degrees C for 4 minutes. Three dimensional atom probe (3DAP) were applied to investigate the elemental distributions of V, Zr and Nb in annealed ribbons. V-enriched intergranular phase with complex characters was found at the grain boundaries.
