“…Therefore, during the plastic deformation, the microstructure and properties of composite can be markedly influenced by the incorporated graphene. Additionally, the size, morphology, and dispersion of graphene can be affected due to the deformation of matrix [ 30 , 34 ]. As a result, it is significant to systematically investigate the evolution of microstructure and properties of Gr/MMCs during the drawing process.…”

The influence of multi-pass cold drawing on the evolution of microstructure, texture, and properties of Cu matrix composite, reinforced by in situ grown graphene, has been systematically investigated. Under continuous and severe plastic deformation, the grains in the composite were continuously refined to nanoscale. In addition, graphene in the composite could be gradually refined, exfoliated, and redispersed. Interestingly, dynamic recrystallization of the composite was formed after 80% drawing reduction and its formation mechanism was discussed. The texture of the as-drawn composite comprised a mixture of fiber textures with dominated <111> and minor <100> orientation after 99.7% severe drawing reduction. The tensile properties and electrical conductivity of the as-drawn composites were also investigated. This work provides a better guideline on the plastic deformation behavior of the advanced graphene/metal nanocomposite.

“…Compared to the conventional pure metals (such as Cu, Al, Mg and Ti) and their alloys, metal matrix composites (MMCs) have attracted great interest in recent years owing to their excellent physical/mechanical properties (including high strength and elastic modulus, high hardness, good wear resistance, and good thermal/ electrical properties) [1][2][3][4][5][6][7][8][9][10]. For examples, Cu matrix composites are preferred for electrical and tribological applications owing to their good electrical and thermal conductivities [11][12][13], whereas Al matrix composites are extensively used in aerospace and automotive industries due to their relatively low density and good workability [2,[14][15]. Titanium matrix composites (TiMCs) have also found wide-range applications in aerospace, automobile and chemical industries due to their light weight, high specific strength and excellent corrosion resistance [16][17][18], however, in many applications, their mechanical and physical properties need to be further improved.…”

“…The obtained composite had a tensile strength of 500 MPa, which was 40% higher than the performance of the Al matrix. Wu et al [ 22 ] studied the effect of multi-pass extrusion on graphene/6063Al composites. It is found that after multiple extrusions, graphene had an obvious interlayer slip, and fewer graphene nanoplates were peeled off from the thick graphene layer.…”

Rolling enables the directional alignment of the reinforcements in graphene/Cu composites while achieving uniform graphene dispersion and matrix grain refinement. This is expected to achieve a breakthrough in composite performance. In this paper, the process parameters of rolling are investigated, and the defects, thickness variations of graphene and property changes of the composite under different parameters are analyzed. High-temperature rolling is beneficial to avoid the damage of graphene during rolling, and the prepared composites have higher electrical conductivity. The properties of graphene were investigated. Low-temperature rolling is more favorable to the thinning and dispersion of graphene; meanwhile, the relative density of the composites is higher in the low-temperature rolling process. With the increase of rolling deformation, the graphene defects slightly increased and the number of layers decreased. In this paper, the defect states of graphene and the electrical conductivity with different rolling parameters is comprehensively investigated to provide a reference for the rolling process of graphene/copper composites with different demands.
