Outline of Final Research Achievements

Mechanical and thermal-electrical properties of metal based composite materials dispersed with carbon nanoparticles were investigated. The dispersion strengthening of carbon nanoparticles through the carbide was expressed by the reaction of the additive element and carbon nanoparticles in the copper alloy. At the same time, the electrical pass of the copper alloy matrix was increased because of the decreasing amount of the elemental solid solution in the matrix. Pure Al powder monodispersed with CNTs was used in the case of Al based composite. Carbides generated in CNT and the matrix was realized a strong bonding between Al matrix and CNTs. This binding caused the CNTs dispersion strengthening.
