Investigation of Mechanical Properties of Aluminium Based Metal Matrix Composites Reinforced With Sic & Al₂O₃

摘要

Present study is focused on the fabrication of aluminium 6061 based metal matrix composites, Reinforced with silicon carbide and Al₂O₃ by stir casting technique. The percentage of one reinforcement particulate is kept constant and varying other and vice versa, namely typeI and typeII composites. The various mechanical tests like tensile strength test, hardness test, wear test and Impact strength performed on the samples obtained by stir casting technique for comparison purpose. The result indicated that the developed method is quite successful and there is an increase in the value of tensile strength, hardness value and Impact strength of newly developed composite having (SiC + Al₂O₃) particulates in comparison to the Aluminium.
