Abstract

This paper investigated the performance of a recycled AA5051 alloy with nano silicon dioxide (SiO2) ceramic strengthening particulates reinforced by stir casting method in terms of flexural strength. Aluminum alloy of series AA5051 alloys were used as matrix materials and novel nano SiO2 ceramic particles of particle size < 50 nm was used as reinforcement particles. To achieve uniform reinforcement distribution in matrix materials, it was casted using a stir casting method at a melt temperature of 720 °C and a stirring speed of 500 rpm. The fabrication of the recycled AA5051 alloy nanocomposite utilized both an experiment group and a control group with a sample size 20 for each group. The results of the experiments were examined using t-test, and the significance level of the flexural strength of fabricated composites and as-cast recycled AA5051 alloy was analyzed. From the experimental observation it was found that the flexural strength of innovative nano SiO2 reinforced recycled AA5051 alloy composites significantly improved 26% owing to higher surface areas between the mixtures.
