“…Therefore, the tensile or compressive stress resulting from drawing can refine the graphene to small pieces. Thick graphene or graphite can be in situ exfoliated into thin graphene during the plastic deformation process, which has been reported in recent investigations [ 30 , 36 , 40 ]. The shear strain induced by deformation is considered to be the inducement for the exfoliation of graphene.…”

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.

“…However, in recent times, the copper graphite composites are widely utilized as bushings and bearings in automobile and electrical industries. The graphite reinforced copper composites are developed by several techniques such as stir casting, SPS, and powder metallurgy [1][2][3][4][5]. Out of which, the powder metallurgy is widely used owing to its medium fabrication cost, complex shapes composites and evenly distributed reinforcements within matrix.…”

In the current study, the prediction of tribological performance of Cu-Gr-TiC composites and correlative with surface topography has been studied. For this purpose, the Cu-Gr composites reinforced with TiC ceramic particles were prepared via the powder metallurgy route. The prepared composites microstructure, mechanical characteristics, and dry sliding wear behaviour were assessed. A pin on disc setup was taken for tribological testing where sliding velocity is 1.5 m/s. Wear behaviour of composites was examined using a central composite design (CCD) with three levels. The wear behavior optimization was accomplished through the utilization of response surface methodology (RSM). The input parameters in RSM consisted of sliding distance, varying load, and weight percentage (wt.%) of reinforcements, while the wear rate and coefficient of friction served as the two responses. An analysis of variance (ANOVA) using RSM was conducted to identify the significant parameters influencing the wear rate and coefficient of friction. A quadratic model was suggested based on best fit and a regression equation was established for predicting the tribological properties at any given input parameter. Comparative of experimental and predicted values shows close tolerance. It was observed that RSM is significant tool to predict and optimize the tribological properties. The composite having 3.08 wt.% of TiC particles was optimized for minimum wear rate & COF at 20 N load and 2000 m sliding distance.
