Abstract
The present research focuses on the synergetic effect of ZrB2-Si3N4 on the properties of AA8011 for service life improvement in automobile components. The hybrid composites were developed by liquid metallurgy route with varying particulates composition of 0% - 20% in a step of 5. The developed composites were subjected to SEM microstructural characterization and mechanical analysis to evaluate their microstructural evolution, microhardness, and tensile strength mechanism. The results show better improvement in the hardness and ultimate tensile strength of the composite when compared with the unreinforced AA8011. The microstructure clearly revealed an even dispersion of hybrid particulates with no clear trace of voids.
