Research topics from publications: Effect of Gd on microstructure, mechanical properties and damping properties of Fe-Cr-Al alloys; Effect of Gd addition on the microwave absorption properties of FeSiAl composite; Isothermal oxidation behaviour of TiAl alloys prepared by spark plasma sintering with the addition of Gd under water vapour at 900 °C; Fabrication and Microwave Absorption Properties of FeSiAl@PANI Composites; Effect of Sc on damping properties, compressive and tensile strength of Fe-Cr-Al alloy. Representative work: Composites of ferromagnetic particles and conductive polymers have potential applications in the wave-absorbing stealth technology. In this paper, FeSiAl@polyaniline (FeSiAl@PANI) composites were prepared through in situ oxidative polymerization. Electromagnetic parameters of the FeSiAl composites were modulated by varying the aniline content. The inhomogeneous interface between amorphous PANI and FeSiAl provides interfacial polarization, charge accumulation, and defects in the PANI layer, which causes dipole polarization and conductive loss, so that multiple loss mechanisms result in the FeSiAl@PANI composites with superior absorbing properties. When 1 g of aniline monomer is added, the low
