Investigation On Improved Thermal Conductivity Of AA6061 By Reinforcing Hybrid Ceramic Particulates Using Stir Casting Method

Abstract

Aluminium MMCs are replacing conventional aluminium alloys in various domains exclusively in transportation. The basic scientific concept here is to improve the thermal conductivity of the conventional aluminium alloys. Stir casting process is mainly used for manufacturing of particulate reinforced metal matrix composite (PMMC). Manufacturing of aluminium alloy based casting composite by stir casting is one of the most economical methods of processing MMC. Properties of these materials depend upon many processing parameters and selection of matrix and reinforcements. Advancements of manufacturing technology would allow incorporating the Aluminium oxide (Alumina) and Graphite (c) fillers of different/varied and also equal volume with molten aluminium. Scanning Electron Microscopy and EDX are necessary to study the various percentages of particle distribution in Al matrix system. Then temperature distribution along the extended surface (fins) would be determined by pin fin apparatus. This is used to calculate average temperature of fins.
