Abstract
The primary objective of this study was to gauge and subsequently analyze the hardness quotient of AA8176 when reinforced with 10% nano graphene. This amalgamation was achieved through an innovative encapsulation method, and the outcome was juxtaposed against the hardness of the as-cast AA8176. A distinctive encapsulation stir-casting technique was the methodology chosen for the fabrication of the samples in both groups. Group 1 was the product of an amalgamation between nano graphene (comprising 10% of the total) and AA8176. Conversely, group 2 exclusively utilized AA8176. Adherence to the ASTM E92 standards was paramount in the preparation of these samples. The hardness of these prepared samples was then discerned by employing a Vickers hardness apparatus. Each of the two groups had a set of 20 meticulously prepared samples. The computational procedure to determine the sample size was anchored in a G-power of 80%, with an α value set at 0.05, resulting in a total sample size of 40. The results revealed that the hardness apex was achieved with the material infused with 10% graphene, registering a hardness uptick of 25% in comparison to the as-cast AA8176. The t-test, a statistical analytical tool, confirmed a marked variance in the hardness mean between the two groups, registering a significant p-value of 0.00 (p < 0.05). Drawing from the evidence and data presented within the contours of this research, one can conclusively infer that the integration of 10% nano graphene into the AA8176 composite markedly elevates its hardness.
