| Summary: | Titanium matrix composites（TMCs），as a new generation of lightweight and high-performance metals are considered to be one of the most promising structural materials in the fields of aerospace，automotive and other high-tech industries. Compared with conventional micron-reinforced TMCs，nano-reinforced TMCs（NRTMCs）exhibit more significant advantages such as the desirable strength and ductility synergies and thermal deformation capacity. However，the performance potential of NRTMCs has not been sufficiently developed due to the problems of dispersion and thermal stability of the nano-reinforcements. How to introduce nano-reinforcements and maintain their stability during thermal mechanical processing has been a serious challenge for NRTMCs. This paper reviews the research progress of the process features，fabrication methods，microstructure characteristics and mechanical properties，analyses and identifies a series of fundamental issues such as dispersion and heat stability of nano-reinforced material that constrain its development，and proposes the directions for future research. The development directions of future research focus on:（1）interface reaction control and thermal stability design；（2）batch production and low-cost preparation technology；（3）research on special thermal deformation and heat treatment process；（4）tissue configuration design and toughness mechanism and （5）other key mechanical properties research of nano-particulate reinforced TMCs. |
