Notes:
CNTs/Fe/Al2O3 nanocomposites were prepared by thermal CVD and SPS methods. Thedispersion of CNTs in the Fe/Al2O3 matrix were controlled by an attrition milling process. FESEManalysis revealed that the CNTs of 5 vol.% were homogeneously dispersed in the Fe/Al2O3. Theeffects of CNTs dispersion on the mechanical and electrical properties of the specimens wereinvestigated. Fracture strength and electrical conductivity of 5 vol.% CNTs/Fe/Al2O3 specimenwere measured at 641 MPa and 2.93 [removed info] 10-11 mS/m, whereas that of a 20 vol.% CNTs/Fe/Al2O3specimen were 208 MPa and 8.46 [removed info] 10-7 mS/m, respectively. In comparison with an Al2O3monolith, the specimen with 5 vol.% CNTs showed enhanced fracture strength and increasedelectrical conductivity
