Research Progress of High-Entropy Alloy Absorbing Materials
With the application and development of wave-absorbing materials in military stealth technology,higher require-ments 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-con-centration 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-en-tropy alloy absorbing materials can be achieved through host element type and concentration regulation,trace element addi-tion,and compounding with other materials.This paper reviews the research progress of high-entropy alloy absorbing materi-als,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.
