Study on Mechanical Properties of Aluminium 6061/SiC Composite by Single and Double Stir Casting Process

Herein, Aluminium 6061 with various weight percentage (1 %, 3 % and 5 %) of Silicon Carbide (SiC-40nm), composite was fabricated by single stir casting (single SC) and double stir casting (double SC) process. Besides, the mechanical properties like hardness, ultimate tensile strength and yield strength of the prepared composites were used to compared the effects of single SC and double SC process. Completely, these properties were enhaced with increment of the reinforcement upto 3%, and then decreased due heterogeneous distribution/ agglomeration. In addition, both processed samples of optimum level of reinforcement (3 % of SiC) morphology and quantitative analysis was carriedout. Overall, the double SC improved the nano particle distribution and mechanical properties than single SC process.
