摘要:

隨著吸波材料在軍事隱身技術(shù)中的應(yīng)用與發(fā)展，對(duì)其性能提出了更高的要求，開(kāi)發(fā)符合“薄、輕、寬、強(qiáng)”且環(huán)境適應(yīng)性強(qiáng)的吸波材料成為當(dāng)前研究的熱點(diǎn)。高熵合金獨(dú)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(shì)，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(chǔ)。高熵合金吸波材料可以通過(guò)主元種類(lèi)和濃度調(diào)節(jié)，微量元素添加以及與其他材料復(fù)合等多種調(diào)控方法來(lái)提高吸波性能。綜述高熵合金吸波材料的研究進(jìn)展，從材料的制備方法出發(fā)，對(duì)其吸波性能的影響因素進(jìn)行詳細(xì)的討論，最后對(duì)高熵合金吸波材料的未來(lái)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.
