Abstract

We investigated effect of annealing temperature on lattice strain of crystalline FeSiAl alloy powders and related electromagnetic absorption properties for crystalline FeSiAl alloy powder-polymer composites. The lattice strain of the microforged FeSiAl alloy powder gradually decreased with annealing temperature and highly relieved by annealing treatment at 700 °C The magnetic saturation significantly increased by the microforging and subsequent annealing treatment due to increase of the stress relaxation. The simulated power loss in the near-field regime showed high electromagnetic absorption over 31% in above 1 GHz because of annealing effect. From simulation results of magnetic field distributions in the near-field, the ferromagnetic metal powder-polymer composite showed excellent electromagnetic absorption in the GHz frequency range.
