Figure 1

TEM images of (a) pristine MWCNTs and (b) chemically treated MWCNTs. (c) SEM and (d) TEM images with EDS element mapping of CuCr powder. (e) SEM image of MWCNT/CuCr mixture. Insets show photographs of wet mixing process. (f) FESEM image of sintered 3 vol.% MWCNT–CuCr composite. Insets show magnified SEM images of MWCNTs having precipitates on the surface and schematic of 2D distribution of CNTs in a plane normal to the SPS compression axis.
