“…Then, now it is well understood that the presence of CNTs has not a perceivable effect on the mechanical properties. From these results, it would be very interesting to check the possible influence of the processing routine (and consequently the CNTs dispersion) or the type of CNTs on the Al2O3 plasticity as it was investigated for 3YTZP-ceramics [18,36].…”

Alumina and alumina/SWCNT nanocomposites have been sintered by spark plasma sintering, obtaining relative densities higher than 99%. Microstuctural characterization revealed a grain microstructure in the submicron range, where alumina/SWCNT nanocomposites exhibited a good CNTs dispersion thought the ceramic matrix. Creep experiments performed in both materials showed a similar mechanical behavior, where the addition of CNTs seems to have a negligible effect on the strain rate, in contrast to results reported by other authors. Grain boundary sliding accommodated by lattice diffusion has been identified as the high temperature deformation mechanisms in both samples, alumina and alumina/SWCNT nanocomposites. We have discussed about the role of CNTs influence on the plasticity of these composites.

“…Incorporation of CNTs in a carbon matrix resulted in a signicant change in mechanical, electrical and thermal properties of carbon matrices. [16][17][18][19][20] Various factors that inuence property modication, are processing techniques, type of CNTs, aspect ratio and CNTs content. However, the nature of interactions between pitch components and carbon nano material during carbonizations has not been claried.…”

In this study, the influence of the addition of carbon nanotubes (CNTs) and carbon black (CB) on the graphitization temperature and microstructure of coal tar pitch (CTP) are investigated. X-ray diffraction patterns of carbon residues indicate that minimum interlayer spacing (d 002 ) values are obtained at 2000C for CTP/CNT. Moreover, the Raman spectrum of CTP/CNTs is similar to graphite, and the relative intensity of Raman lines shows that CTP/CB is less graphitized at 2000 C. In addition, scanning electron microscopy images show that when CB is added sample textures tend to disordered morphologies. However, CNTs, not only improve the morphology of CTP, but also act as nuclei for the growth of graphite flaky crystallites. The role of the CTP/CNT interface and the defects of CNTs on the graphitization degree are studied using transmission electron microscopy, and a mechanism for the graphitization of CTP, in the presence of CNTs, is proposed.
