An experimental investigation on mechanical properties of aluminium-7075 based graphite and bagasse ash particles reinforced metal matrix composite.

Aluminium alloys play a major role in synthesizing parts for the aerospace, automobile, and defence sectors because of their ease of production and modification. The addition of hard-ceramic particles to the aluminium matrix will improve the strength-to-weight ratio. Aluminium 7075 alloy is chosen as a workpiece because of its high strength and low weight. Metal matrix composites, particularly aluminium alloy matrix composites, are suitable choices for industrial applications because of their favourable technical features. In this work, the Aluminium 7075 metal matrix was strengthened with Graphite and Bagasse ash. It was formulated by the stir casting method. The reinforcement was added in three compositions. The machining characteristics are studied by testing its properties such as the microstructure of the specimen and properties of wear. The properties of these specimens are compared with the three compositions that we have produced and the best is chosen among them. The microstructure is analysed using Scanning Electron Microscope (SEM). [ABSTRACT FROM AUTHOR]
