Investigation of mechanical properties of Al6061 with reinforcement of SiC/B4C metal matrix composites

Abstract

The advanced modern manufacturing of aeronautical, automobile, marine industries are required higher in strength, corrosion resistance, and good formability with lesser in weight; these requirements fulfilled by the Aluminium Metal Matrix Composites (AMMCs). In the aluminium alloys, Al6061 exhibits to meet the above requirements of its mechanical and other properties by adding the reinforcement particles to the AMMCs, which improves the mechanical properties. In this research, the article made an attempt to improve the mechanical properties of the Al6061 by adding the reinforcement particles of silicon carbide (SiC) and boron carbide (B4C). The stir casting technique is used for manufacturing the AMMCs with various propositions and their mechanical properties were investigated. The microstructure of the composite was analyzed using Scanning Electron Microscopy techniques. During this investigation, it was found that the reinforcement particles of SiC, B4C are improving the aluminium alloys of Al6061’s mechanical properties in appreciable level.
