A Review on Fabrication Characterization of Hybrid Aluminium Metal Matrix Composite

Abstract

Necessity is the mother of research (Invention), and today’s most important demand of an automobile industry is to reduce energy consumption and pollution in an automobile. This could be done in one way by increasing the efficiency. For the properties like strength, toughness, stiffness to weight ratio, good formability, good corrosion resistance and high machinability must be improved. This challenge could be accomplished by Hybrid Metal Matrix Composites. Hybrid Metal Matrix Composites (HMMCs) are one of the recent advanced materials having the properties of light weight, high specific strength, good wear resistance and low thermal expansion coefficient. These composites materials are extensibly used in structural, aerospace and automotive industries. MMCs are composed of metallic base material called matrix, which is reinforced with a hard ceramic or soft reinforcement. Hybrid MMCs are obtained by reinforcing the matrix alloy with more than one type of reinforcements having different properties. For example SiC could be used as hard ceramic reinforcement and Graphite as soft reinforcement. Thus this research paper is focused on the review of the fabrication and characterization of hybrid metal matrix with summarizing the recent developments covering Aluminium used in manufacturing process.
