    Abstract: Metallic glasses having high permeability, low coercivity, low ac core loss, low exciting power, and high thermal stability are disclosed. The metallic glasses are substantially completely glassy and consist essentially of about 71 to 79 atom percent iron, about 1 to 6 atom percent of at least one member selected from the group consisting of chromium, molybdenum, tungsten, vanadium, niobium, tantalum, titanium, zirconium and hafnium, about 12 to 24 atom percent boron, about 1 to 8 atom percent silicon, 0 to about 2 atom percent carbon, plus incidental impurities, the total of boron, silicon and carbon present ranging from about 18 to 28 atom percent. The alloy is heated treated at a temperature and for a time sufficient to achieve stress relief without inducing precipitation of discrete particles therein. Such a metallic glass alloy is especially suited for use in devices requiring high response to weak magnetic fields, such as ground fault interruptors and current/potential transformers.

    Abstract: A bulk amorphous metal inductive device includes a magnetic core having at least one low-loss bulk ferromagnetic amorphous metal magnetic component forming a magnetic circuit having an air therein. The component has a plurality of similarly shaped layers of amorphous metal strips bonded together to form a polyhedrally shaped part. The device has one or more electrical windings and is easily customized for specialized magnetic applications, e.g. for use as a transformer or inductor in power conditioning electronic circuitry employing switch-mode circuit topologies and switching frequencies ranging from 1 kHz to 200 kHz or more. The low core losses of the device, e.g. a loss of at most about 12 W/kg when excited at a frequency of 5 kHz to a peak induction level of 0.3 T, make it especially useful at frequencies of 1 kHz or more.
