چکیده:

In this study, synthesis of Al-TiO2-multi wall carbon nanotubes composite and effect of multi-wall carbon nanotube (MWCNT) on AL-TiO2 composite has been investigated. Mechanical alloying has been used to mix powders of aluminium, TiO2 powders and multi-wall carbon nanotubes.TiO2 in the amount of 1%, 2% and 3% and carbon nanotubes with 0.5, 1, 1.5 and 2 wt% was used. Al/TiO2/CNT Nano composites were fabricated by isostatic pressing followed hot extrusion techniques. Some properties of different samples of this composite was tested and the results showedthat the addition of MWCNTs improved properties such as tensile strength and micro hardness. The composite were characterized by field emission scanning (FESEM) and Transmission electron microscopy (TEM).
