摘　　要：对非晶合金Fe52Co34Hf7B6Cu1试样进行了中频磁脉冲处理,处理过程中,磁脉冲场强、作用时间保持恒定为1.99×104A/m、10min,脉冲频率分别为500,1 000,1 500和2 000 Hz;用穆斯堡尔谱(MS)、X射线衍射(XRD)和透射电镜(TEM)等技术观察了该非晶合金磁脉冲处理后的微结构变化,并以振动样品磁强计(VSM)测量了试样在磁脉冲处理后的软磁性能。结果表明,对应1 500 Hz、1.99×104A/m、10 min的中频磁脉冲处理,相对优化了合金的软磁性能。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.
