Long-range-ordered Fe3Al with excellent electromagnetic wave absorption

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

“…[5][6][7][8][9][10] In particular, Fe 3 Al-based intermetallic compounds have attracted increasing attention as good magnetic loss absorbers due to their high permeability, low electrical conductivity, excellent oxidation resistance, and good corrosion resistance. [11][12][13][14][15] Tuning the morphology and order degree of Fe 3 Al can signicantly affect its EM wave absorption performance. For example, annealing Fe 3 Al akes 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.…”

A Quantum-Mechanical Study of Antiphase Boundaries in Ferromagnetic B2-Phase Fe2CoAl Alloy

“…Our study is focused on Fe 2 CoAl belonging to a very promising class of materials based on Fe and Al [19][20][21][22][23][24][25][26]. Earlier experimental studies [27][28][29][30][31][32][33][34][35][36][37] are currently complemented by research efforts related to applications in high-temperature coatings [38][39][40][41][42][43][44] and composites [45][46][47][48][49], new preparation techniques [50][51][52][53] and their material properties [54,55]. Theoretical studies of iron aluminides include ab initio calculations of single-phase materials [56][57][58][59][60][61][62][63][64][65] and nanocomposites [66,…”

The Impact of Vibrational Entropy on the Segregation of Cu to Antiphase Boundaries in Fe3Al

“…The Fe 3 Al intermetallic compound belongs to a promising class of Fe-Al-based materials possessing relatively low density, unusual resistance to oxidation, and low cost of raw materials [1][2][3]; some of them suffer from room-temperature brittleness [4][5][6][7][8]. Earlier experimental studies of these materials [9][10][11][12][13][14][15][16][17][18][19] were recently complemented by research focused on their use in high-temperature coatings [20][21][22][23][24][25][26] or composites [27][28][29][30][31], novel preparation techniques [32][33][34][35], and their materials properties [36,37]. Theoretical studies cover quantum mechanical calculations of single-phase materials [38][39][40][41][42][43][44][45][46]…”
