Fabrication and properties of aluminium matrix hybrid nanocomposites by stir casting technique

Abstract

Regular materials like steel, brass, aluminum and so on will fall flat with no sign. Breaks commencement, spread will happens with in a limited ability to focus. Presently multi day to beat this issue, regular materials are supplanted by Aluminum Composite materials. The best alternative for aluminum composite materials is its unique ability to design the materials to provide necessary features. In this paper, classical simple techniques for manufacturing AMMCs with achievable characteristics are explored by dispersing silicon carbide micro and nano particles in the matrix. The matrix and the reinforcement material were chosen for aluminium (A356) and silicon carbide (micro and nano particles). Experiments carried out were a SiCmicro weight fraction for 10%, and a SiCmicro weight fraction varying for 1%, 2%, 3% and 4%. The result showed that the stir casting method was very successful in achieving uniform strengthening dispersion in the matrix. This was obvious by the improvement of properties of composites over the base metal. The increase in hardness, marginals decrease in electrical conductivity and marginal changes in relative density were shown to be aluminum hybrid nanocomposites.
