“…In addition to Al 2 Cu and Al 4 C 3 phases, Deng et al[33] observed the formation of Al 2 CuMg phase while studying Al composites with different CNT contents. The absence of this phase in the current study and other studies[8,16,17,31,32,34] could be attributed to (1) the lower diffusivity of bigger Mg…”

“…While some limited microstructural studies on the CNT reinforced Al composite were reported in the literature [7,16,17], three-dimensional electron backscatter diffraction (EBSD) investigations along different observational planes of the composite are not available, to the authors' knowledge. While the compressive micro-strains were noted to occur in the CNT reinforced composites [17][18][19], which would result in X-ray diffraction peak broadening, no actual quantification of the resultant lattice change is reported.…”

“…Within the last decade, carbon nanotubes (CNTs) have been widely used as reinforcing agents in composites due to their outstanding properties such as excellent elastic modulus, very high thermal and electrical conductivity and high aspect ratio [2][3][4][5][6][7]. However, processing of these composites particularly metal/CNT composites has been rather challenging [8].…”

In this study, the effect of incorporation of carbon nanotubes into pure copper was investigated through friction stir processing (FSP). To this end, FSP has been performed using one and three passes. Moreover, the changes in peak temperature of one-pass friction stir processing performed by tools with different shoulder diameters have been recorded. It was found that for the tool with smaller shoulder, the process temperature peak has been significantly reduced. Remarkable reduction in grain size of Cu/carbon-nanotube nanocomposites was observed as compared with the pure copper. Raman spectroscopy results proved a higher extent of degradation of carbon nanotubes upon increasing the friction stir processing passes. On the other hand, microhardness and wear results showed that as the carbon nanotubes are introduced to the pure copper, hardness of composites processed via one-and three-friction stir processing passes showed enhancements of 65 and 105 %, respectively, and the weight losses were also decreased 31 and 68 %, respectively. It was also observed that friction coefficient of one-pass processed composite is lower than that of the pure copper due to the presence of carbon nanotube clusters. Whereas, the friction coefficient of three-pass processed composite was increased regarding to the pure copper. The reduction in slope of wear weight loss upon increasing the applied force at the wear test signified the higher efficiency of the processed composites under harsh conditions.
