摘要：In this study, FeCoNiCuZn single-phase high-entropy alloy powders were synthesized at room temperature for the first time using high-frequency electromagnetic-field assisted ball milling. FeCoNiCuZn was found to be a type of soft magnetic material exhibiting saturation magnetization as high as 65.92 emu/g. Its microwaveabsorbing properties were investigated in the frequency range of 2-18 GHz. Its minimum reflection loss reached 14.69 dB at 10.96 GHz, corresponding to a thickness of 1.5 mm and effective bandwidth of reflection loss values below 10 dB (90% of microwave absorption) of 2.5 GHz (9.9-12.4 GHz). In order to understand the mechanism involved, a comparative experiment with the same experimental conditions but without the high-frequency electromagnetic field was performed. The results show that a type of non-thermal effect that changes the diffusion ability and solid solution effect of metal atoms exists in the high-frequency electromagnetic-field-assisted ball milling processing.
