In the present investigation, Cu-based MMCs have been developed by PM route using exfoliated graphite nanoplatelets (xGnP) and MWCNTs as nanofillers and their influence on mechanical properties as well as crystallographic texture have been studied. xGnP possesses fine particle size as well as less disorder as compared to MWCNTs. Relative density, hardness and wear resistance found to be increased with the addition of nanofillers upto 2 wt% xGnP/MWCNTs, whereas porosity found to decrease with the addition of nanofillers upto 2 wt%. The hardness of Cu-2 wt% xGnP composite was found to be 560 MPa, which is about 1.6 times higher than that of the pure Cu sample (350 MPa) and 1.2 times greater than Cu-2 wt% MWCNTs composite (475 MPa). The wear mechanism was found to involve a combination of abrasion, ploughing, delamination, microcracks, deep grooves and pullout of nanofillers in all the composites. The tensile strength of the various Cu-xGnP composites shows an improvement upto the addition of 2 wt% xGnP. The maximum tensile strength of 130 MPa was achieved in the case of Cu-2 wt% xGnP composite, which is about 1.7 times higher than that of the pure sintered Cu sample (76 MPa). However, the tensile strength of the various Cu-MWCNT composites continuously decreases with the addition of MWCNTs. The homogenous distribution of xGnP, as well as good bonding of xGnP with Cu matrix, has been observed in SEM and TEM images of composites, which is found to be more dominant as compared to MWCNTs distribution in Cu-matrix. The residual stress in the various composites was found to be compressive in nature, and it shows a similar trend as that of the other properties like hardness and wear behaviour of the composites. The addition of nanofillers also altered the crystallographic texture of the composites. xGnP leads to weaker texture as well as decrees in the volume fraction of 〈011〉 fiber as compared to MWCNTs in Cu-based MMCs, which leads to having superior mechanical properties as compared to MWCNTs composites.
