Abstract

Nanocomposites with aluminium base reinforced with nanoparticles, have wide applications in many industries, for example aerospace, marine, automotive, due to its lightweight, high tensile strength and wear resistance. Microstructure, mechanical, and tribological properties of nanocomposite materials are critical for the reliable and optimal design of novel materials. The reinforcement of micro or nano-sized range particle with aluminium matrix yields improved physical and mechanical properties in composite materials. The microstructure characterisation and mechanical testing of an A356 metal matrix composite with various percentages of graphene (0.1, 0.3, 0.5 % wt) generated by mechanical stirring process are presented in this paper. A356 alloy will be used as the matrix material and nano graphene produce by reduction of graphite oxide method will be added as reinforcement. Following that, the sample will be constructed utilising the cooling slope casting technique. The optimal parameters to get and the globular microstructure of the specimen are stated in the scope. Vickers hardness and tensile strength tests will be used to determine the specimen's mechanical properties. Tensile strength testing will be performed in accordance with ASTM E8M standards
