摘要
Different amounts of absolute ethanol (0-50 mL) are used as process control agents (PCA) to prepare FeCoNiAlCr0.9 high entropy alloy (HEA) powders via 90 h ball milling. The results show that the increased amount of PCA plays an active role in the crystallinity of powders, and regulate the thickness and size distribution of flake particles. As the volume of PCA increases, the real and imaginary parts (epsilon '' and epsilon '') of complex permittivity get increased by the enhancement of the interface polarization and surface polarization, while the increase in the real and imaginary parts (mu '' and mu '') of complex permeability arises from the increased anisotropic energy. The addition of PCA not only promotes the reflection loss but also extends the effective bandwidth (up to 4.28 GHz). Here, the performance adjustment of HEA electromagnetic absorber is realized by forthrightly changing the process parameters of ball milling.
