Synthesis and Mechanical Property Evaluation of Hot Forged Aluminium Alloy Reinforced with Nano Alumina

Abstract:

Metal matrix composites with aluminium matrix and non-metallic reinforcements are popular candidates in automotive, aerospace, sports and military application because of their high strength-to-weight ratio, stiffness, wear resistance, high-temperature resistance, etc. often they are subjected to secondary manufacturing processes like extrusion, rolling, forging, etc. to suit the service requirements. Metal matrix composites reinforced by nanoparticles are very promising materials, suitable for a large number of applications. In the present investigation, nanocomposites have been synthesized by addition of 0.25, 0.5, 0.75, 1 and 1.25 wt% of nanoAl₂O₃ powder in to molten Al 1100-Mg alloy using stir casting method and then hot forged. The mechanical properties such as tensile strength, hardness and percentage elongations were studied for all the test specimens. The 0.75 wt% of nanoAl₂O₃ added forged nanocomposite exhibited higher hardness and 0.5 wt% of nanoAl₂O₃ added forged nanocomposite exhibited higher yield strength, tensile strength and percentage of elongation.
