A Concise View Point on Effects of Agro and Industrial Waste as Reinforcement on Characteristic Properties of Aluminum Alloy-Based Metal Matrix Composites

Abstract

AbstractAluminum alloy-based metal matrix composites preferred over various conventional materials in aerospace, automotive, electronics, defense and marine applications only to their excellent improved properties. Now, these composites made by adding SiC, Al2O3, BN particles into molten Al alloy to make it cost-efficient. Owing to poor wettability of these particulates and the density difference between the particulates and the matrix making the product even costlier. To avoid the above uncommon conditions, researchers have started using industrial waste and agro waste materials as reinforcement which has the potentials of satisfying the demands of advanced engineering applications. Reinforcement materials like fly ash, rice husk ash, coconut shell ash, bagasse ash, eggshell and red mud used to reach optimality in structure and properties of waste materials reinforced metal matrix composite. Many manufacturing techniques have devised over the last three decades. This paper trying to review the various industrial and agro waste reinforcing materials employed in production of aluminum alloy-based metal matrix composites (AMCs). It also explains the way it affects the physical, mechanical and wear properties of the material.KeywordsAluminum alloyStir castingMetal matrix composites (MMCs)Mechanical propertiesTribological propertiesIndustrial and agro waste materials
