Abstract

High glass-forming ability and excellent soft-magnetic and mechanical properties were simultaneously achieved in (Fe,Co)-Mo-(P,C,B,Si) bulk glassy alloys (BGAs). The large BGA with a maximal diameter up to 6 mm was formed by copper mold casting in the alloys, which is the largest size in FePC BGA system. The BGA with a proper content of Co exhibits superhigh initial effective permeability of over 360 90 at 1 kHz and saturation magnetization of over 1.0 T. The fracture strength of the BGA reaches 3370 MPa. This bulk specimen undergoes a plastic strain exceeding 1%, which is the largest for such large ferromagnetic BGAs.
