High-Efficiency UHF Radio-Absorbing Composites Based on Iron Alloys

The use of pure iron in UHF radio-absorbing composite fillers is appraised. A method is proposed for selecting iron-based alloys with improved properties. Experiments confirm that the Fe–Al system with 10–14% Al is the most promising filler for such systems. The main trends in the use of such alloys as broadband fillers for radio-absorbing composites are noted.
