Programmable Metastable Engineering of FeNi 3 –High‐Entropy Oxide Heterostructures for Ultrawideband Electromagnetic Absorption

Bosen Lei, Siyuan Dong, Zhonghua Wang, Jie Han et autres

ABSTRACT Electromagnetic wave absorbing (EWA) materials remain limited by steady‐state thermodynamic design, restricting the use of non‐equilibrium thermodynamic–kinetic competition to tailor intrinsic electromagnetic properties. Here, we report a carbothermal‐reduction‐driven metastable engineering strategy for programmable FeNi 3 –high‐entropy oxide (HEO) biphasic composites on …

Synergistic Dynamic Phase Transformation during Wire Electro-explosion Enables High-Entropy Alloys Nanoparticles with Efficient Electromagnetic Absorption

Liwen Liang, Jian Wu, Xin Li, Huantong Shi et autres

Regulating solid-solution-type alloying and composition-structure evolution is an effective strategy for optimizing electromagnetic matching in high-entropy systems. However, precise control over composition redistribution and phase evolution remains challenging for high-entropy alloy nanoparticles (HEA NPs) synthesized under ultrafast nonequilibrium conditions. Herein, we propose …

Investigation on the corrosion mechanism of W/Cu surfaces and interfaces induced by SF6 under DC arc discharge

Xinwei Zhang, Huai Wang, Hong‐Yu Zhang, Shengchun Yang et autres

随着柔性直流输电技术发展，高压直流断路器对耐电弧烧蚀以及耐灭弧气体腐蚀能力要求提高。铜钨材料因优异性能常用作触头，其性能影响气体绝缘断路器系统安全。本研究通过第一性原理，探究铜钨表界面不同结构在直流条件下的SF6腐蚀性能。结果显示，铜钨功函数与结构相关，铜钨晶界最低（4.28 eV）；SF6气体与钨相吸附更强（-1.17 eV），晶界吸附能最低（-5.80 eV），且阴阳极环境影响显著；腐蚀后功函数与最大应力下降7%。研究为高性能触头设计提供理论支撑。
