Investigation on mechanical properties of Al7075 based MMC reinforced with Fe3O4

Abstract

This work primarily focuses on Metal Matrix Composites due to their immense usage in the engineering industry. Metal Matrix Composites (MMCs) hold considerably improved mechanical properties with huge sort of applications from automotive to aerospace. In this investigation, aluminum (Al7075) as matrix and 3%, 6%, and 9% weight proportions of iron oxide (Fe3O4) as reinforced Metal Matrix Composite are prepared by the help of the stir-casting method. The stir casting process is adopted due to its rewards like easy manufacturing, low manufacturing cost, and uniform distribution of reinforced particles. The reinforcing particle Fe3O4 takes part in a significant function in the engineering material properties. The investigation reveal enhance in mechanical properties like Tensile, Compression and Hardness Strengths. When juxtapose with primordial Al7075 alloy, the tensile strength is recorded highest as 362 MPa and Yield strength as 262 MPa for 9% wt. reinforced Fe3O4. Also, micro structural studies (SEM & EDS) were done on the newly fabricated Al7075-Fe3O4 Metal Matrix Composite which conveys uniform distribution of Fe3O4 reinforced particle.
