Evaluation of aluminium hybrid metal matrix composites by analytical hierarchy process (AHP) method

Abstract

Selection of most appropriate matrix materials plays a pivotal role in the fabrication of aluminium based hybrid metal matrix composites. In order to satisfy the demands offered by engineering fraternity, aluminium based hybrid metal matrix composites (AHMMCs) has become a most promising material with superior mechanical properties, low density, good corrosion resistance and tribological properties. This paper mainly focused on an evaluation of a most suitable matrix material for fabrication of AHMMCs using an Analytical Hierarchy Process (AHP). In this research, selection of a suitable matrix material from AA 6XXX series has been investigated by considering the five criteria such as Density, Tensile strength, Hardness, Melting Point and Cost of available matrix materials in the market. Finally, the result shows that AA 6082 aluminium alloy is the optimum matrix materials for the production of AHMMCs.
