Abstract: |
Porous Fe-Ni alloy powders has been prepared by Fe-N alloy phase-change theory and mature chemical plating techniques, Porous Fe-Ni alloy powder morphology, structure and magnetic constants are tested by the use of optical microscope、X-ray diffraction and Vector network analyzer, etc, the results show that porous Fe-Ni alloy powders which is prepared by Fe-N alloy phase-change theory has a high porosity ,and uniform pore size distribution, in the 6.5 GHz and 11.0 GHz respectively, a significant absorption peak appeared,when the thickness of Fe-Ni alloy powders is 3mm, microwave absorbing properties of composite materials is the best,but when the thickness is 4mm, in the 4～8 GHz frequency range, there is a good wave absorption properties.
