N2 - Flaky FeCrAl particles with different morphology are obtained by ball milling process. The influence of milling time on microstructure, electromagnetic and microwave absorption properties of the FeCrAl alloy are investigated. The spherical FeCrAl particles transform to flaky and the flakiness ratio is improved with the prolongation of milling time. As the milling time increases from 0 to 10 h, the complex permittivity and permeability, as well as the microwave absorption properties of the FeCrAl particles are greatly enhanced. The flaky particles milled for 10 h present the most favorable microwave absorption property. For the sample in 2.6 mm thickness, the absorption bandwidth below −10 dB is obtained in the frequency range of 8.2–12.4 GHz with a minimum RL value of −25.6 dB at 10.3 GHz. The results demonstrate the electromagnetic and microwave absorption properties of the spherical FeCrAl particles can be enhanced via ball milling process.
