In this paper,the amorphous specimens Fe5 2 Co34 Hf7 B6 Cu1 were treated by medium-frequency mag-netic pulsing.The treatment conditions were as follows :the field intensity and acting time were constant (1.99×10 4 A/m,10 min),the pulsing frequency were 500,1 500 and 2 000 Hz respectively.The microstructural change of specimens after magnetic-pulsing were observed by MS,XRD and TEM technique.The soft magnetic properties of specimens treated by magnetic-pulsing were tested by VSM.The results show that the medium-frequency magnetic pulsing(1 500 Hz,1.99×10 4 A/m,10 min)can relatively improve the soft magnetic proper-ties of Fe5 2 Co34 Hf7 B6 Cu1 amorphous alloy.
