Abstract:The powders of amorphous nanocrystalline Fe85Si2Al6Crwere 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.

 

Key words: microwave absorbing mechanism; complex permeability; complex permittivity; ball-milling time
