Effect of Processes Parameter on Mechanical Properties in Aa2218-Fe2o3 MMCS Processed by Stir Casting

Abstract

The experiment is done to find out the behavior of MMCs by stir casting using raw material as AA2218 with Iron oxide (Fe2O3). In AA2218 material Fe2O3 is mixed at different stirrer speeds such as 180, 250 & 400 rpm. After casting is done the specimens are prepared for testing microstructures are taken out and compared with the stirrer cast MMCs microstructures. The mechanical properties are evaluated such as hardness test, tensile strength test and toughness test. The effect of stirring speed and particle content on microstructure, mechanical properties of the composites such as hardness and tensile strength are reported and discussed.
