摘要

Fe_(60)Co_(40) and Fe_(72)Al_(28) nano-alloys were synthesized from elemental powders via high-energy mechanical alloying. The prepared samples were characterized using X-ray diffraction, scanning electron microscopy and X-band waveguide to measure the reflection loss in a frequency range of 9-10 GHz. The XRD patterns show that disordered Fe_(60)Co_(40) solid solution with a body-centred cubic structure is formed for milling times longer than 12 h, and after 4h milling, the solid solution Fe_(72)Al_(28) has been largely formed. Morphological studies indicate an average grain size of 10 to 15 nm. The microwave- absorbing characteristic reveal good performance for compared to Fe_(72)Al_(28), the maximum reflection loss is about -12 dB for the absorber.
