Effect of solid waste materials on properties of magnesium matrix composites - A systematic review

Abstract

The need for light and high specific strength materials in many fields such as automotive and aerospace is increasing day by day. Magnesium (Mg)-based materials have become attractive for many industries thanks to their high specific strength, good vibration damping ability, and recyclability. However, Mg's low strength and wear resistance are important barriers limiting its industrial use. Researchers are developing Mg matrix composites using various reinforcements and expanding the use of Mg-based materials. The conventional reinforcements are Al2O3, SiC, B4C, TiB2, CNT, and GNPs for the production of Mg matrix composites. Researchers have been trying to reduce the cost of Mg matrix composites in recent years by using cheaper and environmentally friendly reinforcements. These reinforcements are solid wastes such as eggshell, fly ash, red mud, and waste glass, and their use in composite systems is becoming more common day by day. This review focuses on the Mg matrix composites reinforced with solid waste particles and the changes in wear, mechanical, corrosion, and thermal properties with the addition of these reinforcements.
