(Fe,Co)–Mo–(P,C,B,Si)块状非晶合金(BGA)同时实现了高玻璃形成能力和优异的软磁和机械性能。最大直径可达6mm的大型BGA采用合金铜模铸造而成，是FePC BGA系统中最大尺寸。适当Co含量的BGA表现出超高的初始有效磁导率，在1kHz下超过360 90，饱和磁化强度超过1.0T。 BGA的断裂强度达到3370MPa。该块状样本承受的塑性应变超过 1%，这是此类大型铁磁 BGA 中最大的塑性应变。
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 6mm 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 1kHz and saturation magnetization of over 1.0T. The fracture strength of the BGA reaches 3370MPa. This bulk specimen undergoes a plastic strain exceeding 1%, which is the largest for such large ferromagnetic BGAs.
