摘要：

Amorphous alloy ribbons Fe60Co26Hf7B6Cu1 (3mm in width and 30 mu m in thickness) were prepared using the single-roller melt-spinning technique. Amorphous specimens were treated by pulsed magnetic field with lower frequency. The microstructure and crystallization of amorphous specimens were investigated by Mossbauer spectroscopy, XRD and TEM etc. The results show that the magnetic pulsing can induce the crystallization of amorphous alloy at low temperature. With the increasing of pulsing frequency, the precipitated fraction and corresponding hyperfine magnetic field of the base metal phase alpha-Fe(Co) is increased.
