Опубликована: Ноя. 9, 2024

Abstract Microwave absorbing materials play an increasingly important role in modern electronic warfare technology for enhancing electromagnetic compatibility and suppressing interference. High‐entropy ceramics (HECs) possess extraordinary physical chemical properties, more importantly, the high tunability of multi‐component HECs has brought new opportunities to microwave materials. Rich crystallographic distortions occupancies enable have highly efficient absorption excellent mechanical thermal stability. Therefore, structural advantages are integrated from comprehensive perspectives, emphasizing on dielectric magnetic properties phenomenon. Strategies proposed improve capacity HECs, including composition optimization, microstructure engineering, post‐treatment technology. Finally, problems obstacles associated with high‐entropy (HEMs) research discussed. The innovative design concepts highlighted.

Abstract High‐entropy boride (HEB) ceramics demonstrate significant potential for cutting tool applications, yet conventional synthesis methods face challenges in achieving full densification and optimal mechanical performance. (Mo 0.2 Zr Ta Nb Ti )B 2 HEB were prepared using the spark plasma sintering‐high‐frequency (SPS‐HF) dual sintering method. The properties of ceramic materials achieved at a temperature 1750°C. Compared with material without Al O 3 (HEB0), containing wt% (HEB3A) exhibited improved properties. Vickers hardness flexural strength HEB3A 20.07 GPa 492.85 MPa, representing increases 2.87% 17.28%, respectively, compared to HEB0. distance 1000 m coefficient friction 0.62 during dry tests on 45 steel, 66.67% increase an 11.29% reduction, HEB0 tool. results indicate that addition improves performance tools. This work shows HEB‐based high hardness, toughness, have applications field
