| 中文摘要 | The effect of Nb addition on the glass-forming ability (GFA), soft-magnetic properties and mechanical properties of [(Co0.65 Fe0.35)0.9 Ni0.1 ]73-xB21.9 Si5.1 Nbx (x=3–6) alloy system were investigated. The results showed that by adjusting the content of Nb, the thermal stability of the supercooled liquid and the GFA increased effectively. With increasing the amount of Nb, the supercooled liquid region (？Tx ) increased from 45 to 65 K and the reduced glass transition temperature (Trg=Tg/Tl) was located in the range of 0.584–0.644. As a result, the [(Co 0.65 Fe0.35)0.9 Ni0.1]73-xB21.9 Si5.1 Nbx bulk glassy alloys (BGAs) with diameters up to 5.0mm were produced by copper mold casting. In addition to thehigh GFA, the Co-based glassy alloys exhibited excellent soft-magnetic properties, i.e., saturation magnetization of 0.53–0.81 T, low coercive force of 0.51–1.75 A/m, and high effective permeability of (1.52–2.53)×10 4 at 1 kHz under a field of 1 A/m. Besides, the Co-based BGAs also exhibited super high fracture strength of 4270–4490 MPa and vickers hardness of 1127–1182. |
