摘 要:<正>The effects of Nb on the microstructure and magnetic properties of(Nd0.9Dy0.1)9.5Fe79-xCo5NbxB6.5(x=0,1)nanocomposite magnets were investigated.A free and uniform microstructure was achieved for the ribbons annealed at 710℃for 4 min,enhancing the interaction coupling between grains and improving the magnetic properties.The results of three-dimensional atom probe(3DAP)indicated that Fe-Nb-B inter- granular phase existed at the grain boundaries,suppressing the grain growth during the crystallization process.The coercivity was improved from 224 to 643 kA/m for the modification of the microstructure,
