Effects of Palm Stalk Ash on Mechanical Properties of Al6061 Reinforced with Graphite by Using Stir Casting Process

This study investigates the mechanical characteristics of an aluminium metal grid composite strengthened with graphite and palm stalk ash. The mechanical characteristics of the samples were examined after adding various amounts of graphite and palm stalk ash to the aluminium metal matrix composite. Stir casting is used to create the hybrid metal composite made up of aluminium. Stir casting is a productive process that is most frequently used to create aluminium hybrid composites. Stir casting is a fluid-state technology in which various reinforcements are mixed with the liquid metal using mechanical stir casting processes after being dried out in a furnace. Thus, the molten composite of hybrid metals was poured into the mould, separated, and cooled. The mechanical properties of the aluminium half breed metal grid composites were noted by conducting tests such as hardness test (HRF), Ultimate Tensile strength (as per ATSM E8), impact test and the microstructure of the samples under different magnification in which the microstructure can be used for particle counting and size determination and for process control. The result obtained from the samples by conducting the tests indicated that the hardness increases and decreases at different proportions and shows similar for both the tensile and impact test. Finally in this evaluation the test results shows the effects of palm stalk ash on the aluminium 6061 metal matrix composite reinforced with graphite.
