| 中文摘要: |
| 高熵合金是近十几年新发展起来的一种全新概念的多元合金，其在物理、化学性能和力学性能方面有很多优点，为了解决高熵合金在摩擦磨损应用方面的局限性，提高其综合力学性能，以高熵合金为基体加入增强相合成的复合材料(HEAMCs)成为金属领域研究的热点。基于此，根据研究现状综述了不同HEAMCs的制备成形方法，从制备方法的优缺点对粉末冶金法、熔炼法、激光熔覆法进行了详细的分析。归纳了HEAMCs中纳米细晶强化及第二相协同强化两个方面的强化机制，分别概括了室温和高温情况下HEAMCs的摩擦磨损性能的研究，最后对HEAMCs目前所面临的挑战及未来的发展进行了讨论和展望。 |

| High entropy alloy is a new concept of multiple alloy developed for the last decade or so, which has many advantages in physical, chemical and mechanical properties. In order to solve the limitations of high entropy alloy in the application of friction and wear and improve the comprehensive mechanical properties, composite materials with high entropy alloy as matrix and reinforced phase (HEAMCs) have become a hot topic in metal field. Based on this, this work summarizes the preparation and forming methods of different HEAMCs according to the research status, and analyzes the advantages and disadvantages of the preparation methods of powder metallurgy, smelting and laser cladding in detail. In this study, the strengthening mechanisms of HEAMCs in nanocrystalline strengthening and the second phase co-strengthening are summarized. Then, the studies on the friction and wear properties of HEAMCs at room temperature and high temperature are summarized, respectively. Finally, the current challenges and future development of HEAMCs are discussed and prospected. |
