摘　　要：多相高熵合金具有灵活且多样的多相组织结构,在高温下表现出良好的组织热稳定性,并能有效平衡高温强度和塑性,使其在高温结构材料方面具有显著的研究价值和广阔的应用前景。目前的研究主要集中在室温性能领域,其高温性能,尤其是多相组织结构与高温性能之间的关系尚需进一步系统分析和阐明。本文整理了近期国内外多相高熵合金的组织结构调控和高温性能方面的研究成果,系统总结了合金的相组成、微观结构、高温性能等方面的研究现状及调控手段,深入探讨了其热变形行为和强化机制,并对多相高熵合金在高温环境应用的发展进行了展望。The multiphase high-entropy alloys(MPHEAs)exhibit flexible and diverse multiphase microstructures,demonstrating excellent thermal stability at high temperatures.They show effectively balance high-temperature strength and ductility,making them highly valuable for research and promising for applications in hightemperature structural materials.Current researches primarily focus on room-temperature properties,a systematic analysis and elucidation of their high-temperature properties,especially the relationship between multiphase microstructures and high-temperature performance,are still needed to be elaborated.This paper reviewed recent research findings on the microstructure control and high-temperature properties of MPHEAs,systematically summarized the phase composition,microstructure,and high-temperature performance,as well as control methods.It discussed the thermal deformation behavior and strengthening mechanisms,and provided an outlook on the development of MPHEAs for high-temperature applications.
