摘要

高熵合金（HEA）增强代表了推进轻质金属基复合材料（lmmc）高性能结构应用的变革性方法。本文综述了HEAs与轻金属（如铝、镁和钛基体）的集成，并强调了其克服传统陶瓷增强材料局限性的潜力。该手稿涵盖了lmmc和HEAs的基本原理，并特别关注微观结构演变，界面结合和强化机制，如负载传递，Orowan环和晶粒细化。此外，还讨论了HEAs对增强复合材料的塑性、硬度、耐磨性和抗拉强度的影响。还探讨了与粒子分散、界面反应和可扩展性有关的挑战。通过整合最近的进展和确定未来的研究方向，本文综述了hea增强lmmc在航空航天、汽车、船舶和能源应用的下一代材料方面的前景。

High entropy alloy reinforced lightweight metal matrix composites: A review of the fundamentals, fabrication, properties, and prospects

High Entropy Alloy (HEA) reinforcements represent a transformative approach in advancing lightweight metal matrix composites (LMMCs) for high-performance structural applications. This review examines the integration of HEAs into lightweight metals such as aluminium, magnesium, and titanium matrices and highlights their potential to overcome the limitations associated with traditional ceramic reinforcements. The manuscript covers the fundamentals of LMMCs and HEAs, and particular attention is paid to microstructural evolution, interfacial bonding, and strengthening mechanisms such as load transfer, Orowan looping, and grain refinement. Furthermore, the review discusses the properties imparted by HEAs and emphasises their role in enhancing ductility, hardness, wear resistance and tensile strength of the reinforced composites. Challenges related to particle dispersion, interfacial reactions, and scalability are also explored. By consolidating recent advancements and identifying future research directions, this review shows the promise of HEA-reinforced LMMCs in enabling next-generation materials for aerospace, automotive, marine, and energy applications.
