摘要:

隨著吸波材料在軍事隱身技術中的應用與發(fā)展，對其性能提出了更高的要求，開發(fā)符合“薄、輕、寬、強”且環(huán)境適應性強的吸波材料成為當前研究的熱點。高熵合金獨特的多主元、高濃度成分組成使之具有成為吸波材料的天然優(yōu)勢，其優(yōu)異的軟磁性、耐腐蝕性、抗氧化性等綜合性能為發(fā)展新型吸波材料提供了研究基礎。高熵合金吸波材料可以通過主元種類和濃度調(diào)節(jié)，微量元素添加以及與其他材料復合等多種調(diào)控方法來提高吸波性能。綜述高熵合金吸波材料的研究進展，從材料的制備方法出發(fā)，對其吸波性能的影響因素進行詳細的討論，最后對高熵合金吸波材料的未來研究方向作出展望。

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�瞖ntropy alloy gives them a natural advantage in terms of being wave�瞐bsorbing 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.
