Suri Journal on Material Science 2347–615X 5 2 35 46 Agro-Industrial Waste, Aluminium Metal Matrix Composites (AMMCs), Stir Casting In the last two decades, the global need for lightweight, high- performance and cost effective materials have increased from conventional to composite materials because they possess a good combination of properties like low density, high strength, improved physical, thermal, and mechanical properties. Aluminium Metal Matrix Composites (AMMCs) are one of the most interesting engineering material alternatives used in sectors like automobile, defense, aerospace, and many other engineering applications. AMMCs are fabricated through various routes like stir casting, powder metallurgy, diffusion bonding, and infiltration process. Amongst these, stir route of casting is the most simple, economical and flexible type. The uses of agro-industrial waste in AMMCs have been getting more attention as they can reduce the overall cost of the composite and also improves some of the physical and mechanical properties like density, hardness, stiffness, specific strength, thermal stability, creep, and fatigue resistance. This paper describes a comprehensive review of the utilization of agro-industrial wastes like rice husk ash, sugarcane bagasse ash, coconut shell ash, groundnut shell ash, and red mud which serves as the reinforcement in the development of AMMCs.
