Synthesis and characterization of nanostructured Fe-Ni alloy whisker
The nanocrystalline γ - (Fe, Ni) alloy whiskers have been prepared by chemical reduction of Fe2+ and Ni2+ ions with potassium borohydride under the function of a dispersant agent PE followed by heat treatment at 600 °C under the protection of nitrogen. Conditions, such as quantity of NaOH, concentration of salts, and species of surfactants, of preparation of Fe - Ni alloy have been discussed. X-ray diffraction (XRD), transmission electron microscopy (TEM) and vibrating sample magnetometer (VSM) characterized the synthesized Fe-Ni alloy. Character, capability and use of the materials have been summarized.
