Abstract

High entropy materials (HEMs) have become a prominent research focus because of their remarkable properties, such as superior thermal stability, mechanical strength, and oxidation resistance, including High entropy alloys (HEAs), high-entropy polymers (HEPs), and high-entropy ceramics (HECs). These unique materials hold significant potential for advanced applications across leading industries, including aerospace, defense, military, biomedical, and chemical sectors. An overview of a diverse range of HEAs, their effects, classification, and various entropy alloy manufacturing techniques is presented to discover the optimized HEAs for significant applications particularly relevant to the aerospace industry. Their exceptional performance in the numerous fields of applications has made HEAs a promising alternative over solitary metals, alloys, and composites. Furthermore, it highlights numerous challenges faced in manufacturing. It presents a detailed analysis of the future scope of their development to enhance their applicability in aerospace and other high-demand fields.

高熵合金：用于太空探索的新一代材料

高熵材料（HEMs）具有卓越的热稳定性、机械强度和抗氧化性等显著特性，包括高熵合金（HEAs）、高熵聚合物（HEPs）和高熵陶瓷（HECs），因此已成为一个突出的研究重点。这些独特的材料在航空航天、国防、军事、生物医学和化工等领先行业的先进应用中具有巨大潜力。本文概述了各种 HEA、其效果、分类和各种熵合金制造技术，以发现优化的 HEA，特别是与航空航天工业相关的重要应用。HEAs 在众多应用领域中的卓越性能，使其成为比单独金属、合金和复合材料更有前途的替代品。此外，报告还强调了在制造过程中面临的众多挑战。报告详细分析了未来的发展空间，以提高其在航空航天和其他高需求领域的适用性。
