Fabrication of Nano Hybrid Metal Matrix Composites through Stir Casting Route: A Review

Abstract

Nanocomposite are the most promising advance multi-phase material, having nano particles in its composition within its structure (size being less than 100 nm) and contain at least one phase with constituents in the Nano-meter size range. The properties of nanocomposites are controlled by the type/size of the reinforcement/nature of bonding and type of processing method. Among the various processes of manufacturing prevalent for discontinuous nano hybrid metal matrix composites, particularly stir casting is accepted as a favorable method, which is also commercially viable. Stir casting is advantageous for mass production of composites for being simple and flexible in nature along with cost effectiveness. As it is low-cost comparably and also offers wide selection of materials. Further, it produces better bonding of reinforcements with the matrix, due to the uniform stirring action.
