Abstract
The nano particles are the most important materials to develop the mechanical properties of the materials due to its grin structure and size. In this investigation deals with the (20–30 nm) Zinc oxide (ZnO) nanoparticles volume participation effect on the AA6070 aluminium alloy composite based on the major mechanical properties like hardness and percentage of elongation. The hardened aluminium alloy is used here due to the better results. The composites were prepared by the stir casting method. The ZnO nanoparticle is increased from zero to 12.5% of volume with 2.5% incremental in each specimen and remaining volume percentage is occupied by hardened AA6070 Aluminium alloy. Among all the specimens 7.5% of ZnO nanoparticle mixed composite have maximum hardness and less percentage of elongation.
