In both aluminum and magnesium composites a good dispersion of the MWCNTs into the metal matrix is clearly seen (Figures 1b and 1c), which proves the success of the sandwich technique to synthesize these kind of composites. Figures 2 shows TEM and HRTEM images for both composites, where the MWCNTs can be observed embedded into the aluminum matrix (Figure 2a) and the magnesium alloy matrix (Figure 2b). The details in Figure 2 let see a good and homogeneous interface between both metal matrices and the MWCNTs, with no evidence of the formation of carbides or any other phase.
