采用压制添加剂对粒径为1400 μm的Fe_（73，5）Cu_（1Nb_3Si_（15，5）B_7非晶粉末进行压制成型，获得了理想的片状取向。纳米晶芯表现出的磁导率高达toe= 6000和Hc= 8 A/m的矫顽场。磁性能可以在很宽的范围内变化，这取决于颗粒尺寸和压力添加剂的含量。
Amorphous Fe73,5Cu1Nb3Si15,5B7powders with a particle size up to 1400 μm were consolidated to cores by using a press-additive, which allows an ideal orientation of the flakes. The nanocrystalline cores exhibit permeabilities up toe= 6000 and a coercive field of Hc= 8 A/m. The magnetic properties can be varied in a wide range depending on particle size and content of press-additive.
