摘要
The composite cores were prepared by compacting milled powders of as-quenched nanocrystalline ribbons Fe-Cu-Nb-Si-B and Fe-Zr-B-Cu with epoxy resin. The real permeability at 1 MHz of Fe72Cu2.5Nb3Si13.5B9 powder core with 5 wt% epoxy resin is 30.9 when compacting under 24 MPa, and is 33.0 when compacting under 49 MPa. The powder cores prepared from as-quenched nanocrystalline ribbons show a. at permeability in a wide frequency range. The transition of permeability spectra from resonance to relaxation can be induced by enhancing the compacting pressure. (C) 2006 Elsevier B. V. All rights reserved.
