Effect of Severe Plastic Deformation on Mechanical Charecteristics of Al-6061:SiCP Composites

Nowadays modern manufacturing system is enforced to find out the new material such as metal matrix composite or ceramic matrix composite. The aim of this research is to invent the aluminium based metal matrix composite such as 80% of Al 6061-20% of SiC and 90% of Al 6061-10% of SiC. The aluminum 6061 alloy based composite is prepared through stir casting route. Then the composite is heat treated at the critical temperature. After heat treatment, the mechanical properties of composite are compared before extrusion and after heat treatment. Mechanical properties of both heat-treated and as fabricated composites showed a high dependence on the ceramic content. The yield, ultimate tensile strength, and the elastic modulus of the material were increased with volume fraction of carbide, whereas the ductility was decreased. The tensile properties are seen to vary significantly with ageing treatment. The highest strengths were obtained for the solution heat-treated and naturally aged Al-6061: SiC composites containing 20 vol. % SiC.
