Study of Microwave Absorbing Performances of Nanometer Fe-Al Solid solution

Keywords： Fe-Al solid solution

In this paper, Fe-Al solid solution was prepared by mechanical alloying technology, and Fe-Al powder was dispersed into unsaturated polyester (UP) with different contents as absorber to form mixture Fe-Al-UP. The results indicate that the alloying process is almost accomplished and most of the particles are nanometer. Meanwhile, the microwave absorbability of Fe-Al-UP samples in frequency from 0.3 MHz to 1.5 GHz was studied. The results indicate that the more the absorber, the better the absorbing property. The absorbing property of Fe-50Al-UP was slightly higher than Fe-28Al-UP.
