Mo-Si复合基超高温结构材料（UHTM）因其熔点高、硬度高、密度适宜等优点，是一种极具发展潜力的新型高温结构材料。作为满足1200-1600℃、氧化性和侵蚀性环境中先进高温结构应用需求的重要材料，它已经引起了航空航天、能源、化工、机械、机械冶金等领域研究人员的关注。本研究可为Mo-Si金属间化合物作为超高温材料的研究和应用提供参考。基于Mo-Si金属间化合物的晶体结构和性能，综述了Mo-Si金属间化合物的制备方法、局限性和改性方法，并对其增强韧性和提高中温性能的研究进展进行了综述。通过文献综述，国内外对Mo-Si金属间化合物的改性研究取得了一定的进展。但其室温脆性高、高温强度不足的问题尚未得到解决。
Mo-Si compound-based ultrahigh temperature structural material (UHTM) is a new high-temperature structural material with great potential due to its high melting point, high hardness, and suitable density. As an important material to meet the demands of advanced high-temperature structural applications in the range 1200–1600 °C, in oxidizing and aggressive environments, it has attracted the attention of researchers in aerospace, energy, chemical industry, machinery, mechanical metallurgy, and other fields. This study could provide a reference for the research and application of Mo-Si intermetallic compounds as UHTMs. Based on their crystal structure and properties, we summarized the preparation, limitations, and modification methods of Mo-Si intermetallic compounds and reviewed the research progress in their toughness reinforcement and medium-temperature resistance improvement. Based on the literature review, there has been a certain level of progress in the research on modification of Mo-Si intermetallic compounds worldwide. However, both the high brittleness at room temperature and insufficient strength at high temperature have not been solved yet.
