Abstract
Fe82Zr7B10Cu1 and Fe81Zr7Mo2B10 amorphous ribbons were prepared by the single by single roll rapid quenching method and isothermally annealed at different temperatures. The thermal behavior, microstructure and magnetic property were investigated by STA, XRD, TEM and VSM. Two kinds of amorphous alloys exhibited different crystallization processes. The precipitated phase was only α-Fe phase in the initial crystallization stage of Fe82Zr7B10Cu1 alloy. Both α-Mn type and α-Fe phases were observed in the initial crystallization stage of Fe81Zr7Mo2B10 alloy. Hc of Fe81Zr7Mo2B10 alloy as-quenched and annealed at low temperature is higher than Fe82Zr7B10Cu1 alloy. However, Hc of Fe81Zr7Mo2B10 alloy annealed at high temperature is lower than the Fe82Zr7B10Cu1 alloy.
