Effect of Heat Treatment on Tensile and Corrosion Properties of LM6 Hybrid Metal Matrix Composite Reinforced with Cenosphere and Red Mud

The increased expectation of automotive, aviation and marine industries pertaining to the enhanced properties and their use in elevated temperature conditions and also corrosive environments leads to the development of the newer material to meet the requirements. The requirements of the automobile and marine applications call for the increased mechanical properties and lower density accompanied with higher resistance to oxidation. Hence the present research work is aimed at the development of Hybrid metal matrix composites (HMMCs) using low-density base material and reinforcements. The aluminum of grade LM6 is preferred material in automobile industries, because it can be cast to any complex geometry and possess good machinability, further upon heat treatment, the properties of LM6 alloy can be enhanced to meet the industry requirements. However, requirements of automobile industries consist of increased mechanical properties, lower density and higher corrosion resistance. Hence, in the present research work, it is aimed to develop newer composite material using LM 6 grade Aluminum alloy as matrix material which is reinforced with varied percent Cenosphere and Red mud.
