Abstract :
In this study, carbon nanotubes (CNTs) reinforced aluminum matrix was synthesized by DPDS for the first time. Planetary ball mill has been used to disperse of CNTs in Al matrix. The effects of the CNTs content and secondary pressing-sintering on properties of the nano-composites were investigated. Mechanical properties of aluminum metal matrix nano-composites samples were characterized using compression and micro-hardness measurements. Enhancements of about 52% in compressive strength and 64% in hardness were observed as compared to pure aluminum (matrix) fabricated under the similar condition by conventional sintering process. The morphology and phase analysis of composites have been studied by SEM, and XRD. This research work shows feasibility of manufacturing CNT reinforced metal composites by DPDS.
