【摘要】 TiAl合金由于高比强度、优异的高温抗氧化性能和抗蠕变性能等特性，成为航空航天领域新兴和极具应用前景的高温结构材料。然而，TiAl合金面临的本征室温脆性和仍然较低的高温强度等问题限制了其大规模工业化应用。复合材料技术是有效解决以上问题的方法之一。本文主要归纳了TiAl基复合材料的常见构型、制备方法、组织特征及力学性能，综述近几年国内外相关研究进展，并展望其未来发展方向，以期为促进TiAl基复合材料的研究与应用提供有益参考。更多还原

【Abstract】 Due to their high specific strength, excellent high-temperature oxidation resistance and excellent creep resistance,TiAl alloys have become new and highly promising high-temperature structural materials in the aerospace field. However,the intrinsic room-temperature brittleness and relatively low high-temperature strength of TiAl alloys limit their large-scale industrial application. Composite material technology is an effective method for solving the above problems. This paper mainly summarizes the common configurations, preparation methods, microstructure characteristics and mechanical properties of TiAl matrix composites, reviews the research progress at home and abroad in recent years, and looks forward to future development directions to provide a useful reference for promoting the research and application of TiAl matrix composites.更多还原
