摘　　要：介绍了脉冲磁压缩的原理和磁压缩开关对软磁材料的性能要求。利用平面流铸造法制备了宽度为25mm的Fe73.5Cu1Nb3(SiB)22.5非晶带材。利用金属氧化物涂层、树脂涂层工艺和磁场热处理制备了64mm×24mm×25mm的Fe73.5Cu1Nb3(SiB)22.5磁芯。Fe73.5Cu1Nb3(SiB)22.5磁芯具有高方形比(Br/Bs=0.84),低矫顽力(Hc=9.04A/m)和低损耗(P0.5T/20kHz=41.64 W/kg)等良好的软磁性能,符合磁压缩开关的性能要求。The principle of pulse magnetic compression and magnetic properties requirements of magnetic compression switch were introduced.The 25 mm wide amorphous ribbons of Fe73.5Cu1Nb3（SiB）22.5alloy were prepared by planar flow casting method.Cores of Fe73.5Cu1Nb3（SiB）22.5alloy were prepared by metal oxide coating,resin coating and magnetic field heat-treatment.The cores of Fe73.5Cu1Nb3（SiB）22.5alloy show high square ratio,low coercive force and low core loss,and they meet the properies requirements of magnetic compression switch.
