Abstract

We successfully prepared the rod glassy samples of (Fe1-xCo x)76Si9B10P5 (x = 0∼0.4) bulk metallic glass (BMG) with the diameters up to 3.0 mm by substituting Fe for a small amount of Co element. A certain amount of Co substitution for Fe contributes to the increase of the glass-forming ability (GFA) while maintaining good mechanical properties (the fracture strength up to 3700 MPa). This Co-added ferromagnetic bulk glassy alloy system also exhibits a higher saturation magnetization of 1.49 T and lower coercive force (H c, 1.2 A/m). The Fe-based BMGs with alloying a small amount of Co element demonstrate excellent combination of high GFA, good soft-magnetic properties as well as high strength.
