摘要

Developing novel microwave-absorbing materials is crucial for both military and civil applications. High-entropy alloys (HEAs) microwave-absorbing materials have gained attention due to their unique microstructure and exceptional microwave absorption properties. This work reviews the advancements in HEAs microwave-absorbing materials, covering electromagnetic microwave absorption principles and property evaluation methods. Then, the preparation methods are outlined, including mechanical alloying, vacuum gas atomization and etc. Additionally, key factors influencing the absorption property, such as microstructure, morphology and composition are summarized, and the advantages of HEAs as emerging microwave-absorbing materials are also highlighted. Based on the above, future research directions are proposed, emphasizing the microstructure-property relationships, optimizing preparation processes and designing multifunctional microwave-absorbing materials. This work aims to guide fundamental research and application of a new-generation of high-efficiency HEAs microwave-absorbing materials.
