Parametric based influence of silicon carbide particulates on tensile and hardness characteristics of graphitic aluminium copper alloy

What is it about?

Composites of aluminium alloy have strength comparable to conventional metals. Copperas an alloying element results in improved strength of aluminium. Silicon carbide and graphite also yield better strength when reinforced to aluminium alloys. Graphite has additional advantage due to its solid lubricant characteristic. Effect of silicon carbide and graphite on tensile strength and hardness are studied by varying reinforcement of silicon carbide the percentage of which is based on design of experiments. Tensile strength along with hardnesshas increased with 0 – 8 % SiC reinforcement. These values are further improved upon additionof graphite as secondary reinforcement in the hybrid composites. This can be attributed to uniform distribution of reinforcements as reveled by Scanning Electron Microscope images.
