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.
