Strengthening of copper by carbon nanotubes

The influence of a modifier based on multi walled carbon nanotubes (MWCNT) is investigated using C11000 copper alloy. The influence of the modifier addition into the melt was investigated using tensile test, hardness measurements, X-ray diffraction method and microstructural investigations. It was evaluated that the yield and tensile strengths of the metal increased due to the microstructural changes in the formed metal after addition of 0.01wt.% of the MWCNTs. It was also evaluated that the addition of mentioned amount of MWCNT into alloy has no influence to the phase composition of the formed metal.
