Experimental study on tensile strength of Al2024/SiC/FA/Graphite hybrid MMC prepared by stir casting

Aluminium Metal Matrix Composites (AMMC) have attracted a lot of attention as a result of their high demand in engineering applications since they have excellent mechanical qualities. FA/SiC/Graphite was employed as reinforcement in Al-2024 to create an Al-MMC in this investigation. To minimise the cost of composites, researchers are looking at using naturally accessible materials as reinforcement. The goal of this project is to fill a gap in the present literature by conducting detailed investigation on the strength and wear behaviour of the aluminium alloy AA2024/FA/SiC/Graphite. Four distinct composites, total amounts of 5%, 10%, 15% and 20% by wt.% of FA/SiC/Graphite powder were mixed in equal proportions in Al 2024 via stir casting. Mechanical properties such as tensile strength and wear resistance have all been assessed for the prepared samples. The microstructural examination was also used to look at the reinforcement distribution in the matrix. The micrograph obtained was compared to the mechanical characteristics acquired. The maximum UTS of the first reference specimen, made of pure Al2024 alloy, was 113 MPa. When FA, SiC, and graphite are added in constant volume fractions of 0 percent, 5 percent, 10 percent, 15 percent, and 20 percent, the tensile strength of Al2024/FA/SiC/graphite hybrid MMC is reduced. The ultimate tensile strength of the developed Al2024 hybrid MMCs varies between 90 and 115 MPa depending on the reinforcing combinations tested. Copyright (c) 2022 Elsevier Ltd. All rights reserved.
