Analysis of the Upshot of Heat Treatment on Properties of Magnesium Hybrid Composites

Abstract

Magnesium-based materials are in superior demand in auto industries due to their improved properties and behavior. However, processing and further post-treatment of this kind of magnesium composite is a stimulating chore because of its characteristics. In particular, heat treatment of this kind of magnesium composites may induce a change in grain structure which in turn alters the properties according to the need. So, this article is chiefly focused on the fabrication of magnesium composites by filling with SiC and graphite. According to the Taguchi array, the composites were developed by altering the reinforcing material content, stirring period, and rate. Four samples were fabricated accordingly by employing the stir casting technique. The fabricated composites were exposed to diverse forms of heat treatment processes such as annealing, normalizing, tempering, and quenching to learn the upshot of the same on its behavior. The surface structure of the dispersions in the developed composites was analyzed using an optical microscope, and the mechanical and physical behavior like strength, density, wear, and tensile tests were done on the developed samples. The morphology and behavior of the fabricated composites were compared and analyzed pre and post-heat treatment. Keywords. Magnesium Hybrid Composites, Stir Casting, Heat Treatment.
