摘要
The powders of amorphous nanocrystalline Fe85Si2Al6Cr7 were prepared by high energy ball milling for different times,and measured by XRD and network analyzer. The results show that:1) nanocrystalline microstructure remarkably improves the microwave permeability,and the permittivity is controlled effectively;2) by adding proper dyeing auxiliary(such as copper phthalocyanine),the magnetic properties of powders are improved when the particle sizes milled are excessively small.
