Application of Multi-Criteria Decision-Making Techniques in the Optimization of Mechano-Tribological Properties of Copper-SiC-Graphite Hybrid Metal Matrix Composites Anbesh Jamwal, Rajeev Agrawal, and Pallav Gupta Abstract Cu-MMC with hybrid reinforcements are the attractive research area for heat exchanger, automobile and thermal management applications. The advanced properties of Cu based MMCs make them a promising choice in engineering and other material selection for many applications. There are many fabrication methods by which copper metal matrix composites can be produced, among them stir casting and powder metallurgy are famous one. In the last few years, optimization of reinforcement content, physical properties and mechanical properties of advanced composite materials have enhanced the research area of metal matrix composites. Among the optimization techniques, TOPSIS methodology is popular. In the present book chapter, Copper-SiC-Graphite hybrid metal matrix composites were prepared by liquid state stir casting process. Microstructural, Physical, Mechanical and Tribological behaviour of copper composites is investigated. It is found that the density of composites starts decreasing with increase in reinforcement content. Ultimate Tensile strength and wear resistance of fabricated copper-based composites is improved at the higher reinforcement content. TOPSIS methodology is adopted to optimize both the physical and mechanical properties of Cu-MMC. It is expected that this study will be beneficial for future research directions in the optimization of properties for metal matrix composites as well as hybrid metal matrix composites.

7.1 Introduction Through the ages, man has become more innovative in discovering new forms of materials to make his life more pleased and comfortable. As we know, materials are deeply seated in human’s life. All the human needs such as transportation, communication, construction and even the basic daily needs depends on the materials. In the last few decades, there is a rapid change in human needs and desires which gives some advanced forms of materials with better properties from metals, non-metals, and even alloys. Materials play a very important role in human life [1]. Copper metal matrix composites are capable material to meet the present engineering demands. Copper is widely used metal all over the world, which is used in various engineering applications. The limited properties of pure metal limit its appli
