Abstract:

Discontinuously reinforced titanium matrix composites (DRTMCs) have many excellent properties such as high specific strength, low density, superior corrosion resistance, which have become ideal candidates for aerospace,defense industry and transportation field and have a wide range of applications. Graphene, as a two-dimensional carbon nano “star” material with excellent intrinsic physical and mechanical properties, has been regarded as a promising nano-reinforcement for DRTMCs in recent years. Recently, domestic and foreign researchers have been focusing on solving the key issue of severe interfacial reaction caused by traditional high-temperature sintering through rapid low-temperature consolidation as well as powder modification,established a precise interface control method for graphene-reinforced Ti composites, and optimized the configuration to realize the graphene nanoplatelets intrinsic strengthening. The present work summarized the fabrication and design method of graphene reinforced titanium matrix composites in recent years,investigating the effects of interface reactions, interface structure and micro-configuration or other key factors on the mechanical properties, failure mechanism, and prospected the development trend of graphene reinforced titanium matrix composites in the further.
