Fabrication and characterization of magnesium hybrid composites

Abstract

Lightweight magnesium-based constituents are acquiring an extensive assortment of uses owing to their improved properties and behavior. Hybrid development of these materials can still further advance these characteristics. Rigorous exploration in the arena of cutting-edge lightweight composites is more concentrated nowadays. Accordingly, labors were made to alter the prevailing development trials to advance the competence of the prevailing composites and to analyze the effect of handing out constrictions on the characterization of the composites. So, the main objective of this paper is to focus on the production and characterization of magnesium amalgam composites by filling graphite and silicon carbide in the base metal. The composites were developed by altering the filler content, stirring duration, and speed according to the Taguchi array. Four samples were fabricated accordingly by employing the stir casting technique. The morphology of the dispersions of the developed composites was analyzed using an optical microscope and mechanical and physical behavior like hardness, density, wear, and tensile tests were performed on the developed samples. Taguchi analysis was employed to study and optimize the upshot of the processing constraints on the behavior of the same. The maximum hardness value of 55.4Hv, the density of 1.943 g/cm3, and UTS of 200 N/mm2 are detected at the optimized parametric constraints of the process through S/N plots via Taguchi Analysis.
