Comparative Study on Hardness Strength of Novel Metal Matrix Composite of Aluminum Alloy AA5083 with 0% and 2% SiC Powder Reinforcement

P Naga Sai Rohith, D. Vinodh and L. Natrayan

Abstract

This experimental study aims to relate the hardness strength of the as cast aluminum alloy AA5083 and the metal matrix composite AA5083 reinforced with 2% volume of silicon carbide (SiC) nanoparticle. Composites were produced in two groups using the stir-casting method. The aluminum alloy strengthened with SiC nanoparticle composite without filler of 20 sample specimens were used as the control group and the aluminum alloy reinforced with SiC composite of 20 sample specimens were used as the novel composite the experimental group. The ASTM-D2583 standard was followed for the tensile testing specimen. The G-Power used for determining sample size is 80%. The as cast AA5083 shows a mean surface hardness of 57.06 BHN whereas the metal matrix composite of AA5083 + 2% nano SiC gives mean surface hardness of 71.46 BHN. The independent sample t-test gives a significance of p = 0.001 (p < 0.05). Within the limits of the study and the results obtained from the t-test, the hardness of the AA5083 material increases by 25% relatively for samples containing 2 wt.% novel SiC microparticles as filler materials.
