Abstract
In thepresent study, preparation and characterization of LM6 (A413) aluminum alloy reinforced with nanoalumina powder (Al2O3) is investigated. Al2O3 nanopowder reinforced LM6 (A413) aluminum alloy Metal Matrix nanoComposites (MMNCs) were prepared by stir casting method. The distribution of reinforcement of alumina nanoparticles in LM6 (A413) aluminum alloy were observed with a scanning electron microscopy (SEM). The effect of Al2O3 nanoparticles on mechanical properties of MMNCs were investigated. The wear behavior of MMNCs against hardened steel under dry sliding condition was evaluated on friction wear tester. The results revealed that the inclusion of 2.5% weight fraction alumina nanopowders into LM6 (A413) aluminum alloy enhanced the hardness, impact strength and wear resistance compared with reinforcement of 1, 1.5, 2.5, 5% weight fraction alumina nanopowders. However, the better tensile strength is achieved with 1.5% weight fraction reinforcement in the composites.
