N2 - The effect of Nb addition on the glass-forming ability (GFA), mechanical and soft-magnetic properties in (Co0.942Fe0.058) 72-xNbxB22.4Si5.6 alloys system was investigated. In addition to the increase of glass-forming ability, the increase of Nb content was found to be effective for the improvement of mechanical and soft-magnetic properties. By copper mold casting, Co-based bulk glassy alloys with diameters up to 4 mm were formed in (Co0.942Fe 0.058)67Nb5B22.4Si5.6 glassy alloy. The bulk glassy alloys exhibit a superhigh fracture strength of 2980-3600 MPa and Young's modulus of 121-166 GPa. The bulk glassy alloys also exhibit excellent soft-magnetic properties, i.e., high saturation magnetization of 0.6 T, low coercive force within 0.2-0.5 A/m, high permeability of 47165 at 1 KHz and zero magnetostriction.
