Abstract
Present work focused on fabrication of AA8011-TiO2 composites mixed with various proportions of TiO2 nanoparticles (0, 3, 6, 9, and 12 wt%) by using stir casting technique. The effects of relative percentages of nano TiO2 (with average particles size range 20–50 nm) on composite microstructure, hardness and tensile behaviour have been studied. Using X-ray diffraction (XRD) and scanning electron microscope (SEM) the structure and morphology of the composites have been examined respectively. The microhardness, ultimate tensile strength, yield strength of the composite increased with increasing the percentage of TiO2 particles along the broadening of full width at half maximum of XRD peak. The maximum ductility possessed by the AA8011 matrix itself, which is decreased as increasing TiO2 percentage in the composites. The presence of hard TiO2 particles in AA8011 matrix caused the composite to fracture in brittle mode in the tensile tests. The maximum hardness and tensile strength are shown by the composite with 12 wt% of TiO2 nanoparticles in this study.
