Characterisation of aluminium alloy (Lm6) metal matrix composite reinforced with copper slag/ferro sand

Abstract

Metal matrix composites are found to be one of the promising materials for advanced engineering application. It now has been produced commercially. Recent researches have shown an increased affinity towards the usage of agricultural waste as well as industrial waste as a reinforcement in the composite production which will have a momentous impact on the cost effectiveness of the composite manufacturing. This also will help in sustainable waste management. One of such industrial waste is Copper slag (CS), huge quantity of waste is left as land fill, the compositions of the CS is commensurable to the composition of the fly ash. This entailed using CS as the reinforcement in this composite Fabrication. In this work Aluminium alloy is reinforced with CS to produce a metal matrix composite using stir casting process, as it is one of the cost effective and efficient method of making ALMMC. All the samples are prepared as per ASTM standards and the properties such as Tensile strength, Elongation, Micro Hardness, Specific wear rate, Wear rate and microstructures are examined.
