DEVELOPMENT OF AA2218-Al2O3 MMCs AND CHARACTERISATION FOR MECHANICAL PROPERTIES

Abstract

The experiment is done to find out the behaviour of Metal Matrix Composite made by casting using raw material of aluminium alloy 2218 with alumina (Al2O3) with variable speed of stirrer. Metal Matrix Composite is made by melting the aluminium alloy 2218 at 850⁰C in muffle furnace by adding Al2O3 using stirrer at different speed in the preheated solid state. Addition of Al2O3 is used to increase the mechanical strength. Hardness and toughness both can be increased by adding Al2O3. Microstructure is also checked to know the location of the additive particles in the aluminium alloy 2218. Tensile strength of MMCs is checked on tensometer, hardness is tested on Vicker hardness testing machine, toughness is tested by charpy test.
