An Experimental Study on the Influence of Micrographite on the Improvement of Mechanical Characteristics of A356 Microcomposites Processed via the Stir Casting Route

Abstract

A composite is a combination of two or more insoluble materials that have greater characteristics than all of their individual constituents. The current study focuses on manufacturing and testing the mechanical characteristics of A356 alloy composites reinforced with micrographite particles at different weight fractions of 0%, 5%, 10%, and 15%. According to the findings, including micrographite particles up to 10% wt. increases the bulk hardness, tensile strength, and compression strength of the A356 alloy matrix. In addition, scanning electron microscopy (SEM) was employed to inspect the tensile-fractured surfaces of the fabricated composites.
