The effect of sintering temperature on Cu-CNTs nano composites properties produced by PM method
In this research work, copper and CNTs have been processed using high energy
milling in different milling times (5, 10 and 15 hours). FESEM and XRD have
been used to characterize the milled powders. The FESEM micrographs of the
milled powders indicated that the morphology of powders changed from
spherical shape to flake as milling time increased. The effect of sintering
temperature as well as CNTs content on the properties of Cu-CNTs
nanocomposite has been investigated. The optimum sintering temperature to
produce Cu-CNTs nanocomposites is determined to be 900 oC. The
microstructure and phase analysis of Cu-CNTs nanocomposites were studied by
field emission scanning electron microscopy and X-ray diffraction.
Mechanical properties of nanocomposite samples at various sintering
temperatures were investigated. Cu-CNTs nanocomposite with 4 vol.% CNTs
fabricated by powder metallurgy method indicated the highest value of the
micro-hardness and bending strength as compared to pure copper
