| Abstract: | FeSiAlCr powders were prepared by mechanical alloying(MA) with analytical-purity Fe,Si,Al and Cr powders.The morphology and microstructure of as-milled powders were investigated by SEM and XRD respectively.Electromagnetic parameters were measured with a microwave vector network analyzer,and reflectivities of the powders were calculated.The results showed that the powders were flaky,and the size was about 3um after 80h milling by MA.The diffraction peaks of Si and Al were disappeared with the increasing mill... |
