Improved mechanical properties in titanium matrix composites reinforced with quasi-continuously networked graphene nanosheets and in-situ formed carbides

In order to construct quasi-continuously networked reinforcement in titanium (Ti) matrix composites, in this study, Ti-6Al-4V spherical powders were uniformly coated with a graphene nanosheet (GNS) layer by high energy ball milling and then consolidated by spark plasma sintering. Results showed that the GNS layer on the powder surface inhibited continuous metallurgy bonding between powders during sintering, which led to the formation of...
