The effects of Ni substitution on the magnetic properties of as-cast and annealed Fe-Co amorphous alloy wires

Amorphous alloy wires of composition (Co x Fe y Ni z )72.5Si12.5B15, with Ni substituted for both Co and Fe, were prepared by the rotating water bath chill cast technique. The maximum Ni content that can be substituted in order to cast amorphous wire is reported. The effects of Ni addition on the hysteresis loop parameters and the major magnetic properties of the as-cast wire are reported
