Abstract：Discontinuously reinforced titanium matrix composites, especially in-situ titanium matrix composites, possess excellent mechanical properties and have broad application prospects in aerospace, marine engineering and other national defense fields. The research system in this kind of materials mainly realizes multiple and multiscale strengthening as well as toughening by in-situ microparticles or mixing with nano-reinforcement. However, it is found that compared with micro reinforcements, nano-reinforcements (ceramic nanoparticles, carbon nanomaterials, etc.) are characterized by larger specific area and splendid comprehensive properties. By tactfully designing the microstructure of nano-reinforcements, optimizing the interface of nano-reinforcements and the reinforcement/matrix interface as well as controlling the distribution of nano-reinforcement through the configuration, the development of discontinuously nano-reinforced titanium matrix composites (Nano-reinforced DRTMCs, NRTMCs) can greatly improve the comprehensive mechanical properties of the composites. Therefore, this review mainly summarizes the various preparation methods and technologies of NRTMCs in recent years, deeply discusses the influences of interface structure and spatial configuration on the mechanical properties of NRTMCs, puts forward the essential difficulties and the solutions of NRTMCs at the present stage, and looks forward to the prospective development trend and potential applications of NRTMCs.
