摘要:: 随着吸波材料在军事隐身技术中的应用与发展，对其性能提出了更高的要求，开发符合“薄、轻、宽、强”且环境适应性强的吸波材料成为当前研究的热点。高熵合金独特的多主元、高浓度成分组成使之具有成为吸波材料的天然优势，其优异的软磁性、耐腐蚀性、抗氧化性等综合性能为发展新型吸波材料提供了研究基础。高熵合金吸波材料可以通过主元种类和浓度调节，微量元素添加以及与其他材料复合等多种调控方法来提高吸波性能。综述高熵合金吸波材料的研究进展，从材料的制备方法出发，对其吸波性能的影响因素进行详细的讨论，最后对高熵合金吸波材料的未来研究方向作出展望。

Abstract:: With the application and development of wave-absorbing materials in military stealth technology, higher requirements are put forward for their performance. Developing wave-absorbing materials that are “thin, light, wide, and strong” and with excellent environmental adaptability is a critical research topic. The unique multi-principal elements and high-concentration composition of highentropy alloy gives them a natural advantage in terms of being waveabsorbing materials. Its excellent soft magnetic properties, corrosion resistance, oxidation resistance, and other comprehensive properties provide a basis for research into the further development of novel wave-absorbing materials. Optimized absorbing properties of high-entropy alloy absorbing materials can be achieved through host element type and concentration regulation, trace element addition, and compounding with other materials. This paper reviews the research progress of high-entropy alloy absorbing materials, discusses in detail the factors influencing their absorbing properties from the preparation methods of the materials, and finally gives an outlook on the future research directions of high-entropy alloy absorbing materials.
