摘　　要：高温钛合金及钛基复合材料因具有比强度高、比刚度高、耐腐蚀、耐高温等优异性能,近几年来受到了广泛的关注。钛基复合材料的力学性能往往与增强相组织有关,增材制造技术的快速凝固可以使颗粒增强钛基复合材料中晶粒细化,力学性能得到提升。本文综述了高温钛合金及钛基复合材料的研究进展,分析了增强相组织对材料力学性能的影响,总结了增材制造技术制备钛基梯度功能材料的应用。通过增材制造技术制备钛基复合材料不仅可以提高复合材料的硬度和强度,还可以提高复合材料的延展性,采用增材制造技术制备高性能钛基复合材料将会成为未来的发展趋势。High temperature titanium alloys and titanium matrix composites(TMCs)have attracted the extensive attention in recent years due to the excellent properties,such as high specific strength,high specific stiffness,high corrosion resistance,and high temperature resistance.The mechanical properties of the titanium matrix composites are often related to the reinforcing phase microstructures.The rapid solidification of additive manufacturing technology can refine particles and improve the mechanical properties of the particle-reinforced titanium matrix composites.The research progress of high temperature titanium alloys and titanium matrix composites was reviewed in this paper.The influence of the reinforcing phase on the mechanical properties of the titanium alloys and titanium matrix composites was analyzed,and the application of additive manufacturing technology used for the titanium-based gradient functional materials was summarized.The additive manufacturing technology can not only improve the hardness and strength of the particle-reinforced titanium matrix composites,but also increase the ductility of the composites,which will become the future development trend.
