摘要

Rapidly quenched Co-Fe-B-Si-Nb-(Ga) ribbons were investigated. We have concentrated on the influence of small addition of gallium (2 at.%) into base composition Co47Fe20.9B21.2Si4.6Nb6.3 on structure, thermal and magnetic properties in as-cast state and upon transition to nanocrystalline state. Structure of the samples was examined by X-ray diffraction (XRD), transmission electron microscopy (TEM) and high resolution electron microscopy (HREM). Thermal stability associated with glass transition temperature (Tg), crystallization temperature (Tx) and supercooled liquid region (ΔTx=Tx−Tg) were examined by differential scanning calorimetry (DSC). The Curie temperature of the investigated ribbons was determined by magnetic thermogravimetry analysis (TGA).
