Optimizing the order degree of plate-like Fe3Al for high-performance electromagnetic wave absorption

Enhanced microwave absorption performance of Fe3Al flakes by optimizing the carbon nanotube coatings

“…Fe 3 Al flakes were prepared according to our previous study. 16 A mechanical alloying method was used to prepare a Fe(Al) solid solution. More specifically, Fe and Al metal powders with an atomic ratio of 7 : 3 were mixed in a 500 mL zirconium oxide ball milling tank, which was then located in a QM-3SP2 high-energy ball milling machine (Nanjing University).…”

“…For example, annealing Fe 3 Al flakes at 500 °C generated the most DO 3 superlattice structure, exhibiting an effective absorption bandwidth (RL ≤ −10 dB) of 7.2 GHz with a thickness of 1.35 mm. 16 Nevertheless, some issues such as relatively high density and unsatisfied EM wave absorption properties should be properly addressed for possible scale-up applications. To achieve excellent EM wave absorption performance, effective impedance matching and strong attenuation are important.…”

Effect of Process Parameters on the Microstructure and Wear Resistance of Fe3Al/Cr3C2 Composites

“…Therefore, the development and application of high-strength, wear-resistant materials is urgent. Fe 3 Al alloy and its composite materials have good resistance against wear, high temperatures, and oxidation [1][2][3][4][5][6]. Due to the high content of Fe and Al in the Earth's crust and the low cost of these two elements, the large-scale application of Fe 3 Al also has particularly high economic value.…”
