Experimental Investigation on Tensile Strength of AA4032 Reinforced Nano Si3N4 Composite Subjected to Novel Encapsulate Technique

Hemachandran Bharath Ram, Lakshmaiya Natrayan and Titus Richard

Abstract

This study evaluated the tensile strength of AA4032, both in its as-cast form and when reinforced with 10% nano Si3N4 (Silicon nitride), using a unique encapsulation technique alongside the stir-casting method. Two groups were formed: Group 1 used as-cast AA4032, while Group 2 utilized a composite of AA4032 and 10% nano Si3N4. The production of 20 samples per group adhered to ASTM E08-8 standards, and their tensile strengths were assessed using a universal testing machine (UTM-Auto instrument). With a total sample size of 40, determined by a G-power of 80% and α = 0.05, the nano Si3N4-reinforced composite exhibited a tensile strength increase of 48% compared to the as-cast AA4032. Statistical analysis using the t-test highlighted a significant difference in tensile strength between the groups (p < 0.05), with a p-value of 0.00. The results underscore that reinforcing AA4032 with 10% nano Si3N4 significantly augments its tensile strength.
