N2 - In this study, a micro-laminated structure of titanium matrix composite with uniformly dowel-like and aligned multi-layer graphene (MLG) is fabricated by flake powder metallurgy. High energy ball milling method is applied to efficiently obtain flaky Ti powders with embedded MLG flakes. Spark plasma sintering (sps) which can enable the MLG to preserve its original structure. Also, it can consolidate mixed powders to obtain the laminated billet. Subsequent hot-rolling (HR) is applied to control the degree of interfacial reaction and reduce the internal defection of composites. Results show that interface of the composite owns one in-situ formed TiC thin layer between MLG and matrix. Also, the composite with micro-laminated structure shows significant improvement of strength. Consequently, a uniform disperse of only 0.1wt% MLG enables the as-designed composite to exhibit 218% increase of yield strength compared to monolithic matrix.
