N2 - We investigated the effect of magnetic field heat treatment on electromagnetic wave absorption properties of FeCoNiCr alloy powders. The electromagnetic wave absorption properties of FeCoNiCr alloy powders for as-prepared, heating without magnetic field, and heating with magnetic field of 10 T are compared. The as-prepared FeCoNiCr alloy powders were fabricated by mechanical alloying with mixture structure of BCC and FCC, then the structure of powders transformed from mixture-phase of BCC and FCC to FCC-phase. The results indicate that the heat treatment with magnetic field is critical to the electromagnetic wave absorption properties of FeCoNiCr alloy powders when blended with 40 wt% in paraffin-based samples. The reflection loss (RL) of as-prepared FeCoNiCr alloy powders is only −20.93 dB. However, FeCoNiCr alloy powders heating with magnetic field exhibit the best RL of −60.96 dB and FeCoNiCr alloy powders heating without magnetic field show a RLmin of −32.58 dB. The present work has a significant potential for development of EM wave absorbing materials with magnetic field heat treatment.
