Aluminium Metal Matrix Composite : Composite Material as an Alternative in Automotive Engine

Abstract: The present work aims to develop Aluminium metal matrix composites by incorporating of reinforcements such that combination of best properties could be achieved. The metal base was selected was Aluminium 6082 and it is reinforced with varying volume percentage of Alumina oxide and Fly ash. These AMC were developed by using stir casting technique, in which predetermined reinforcement is added to the molten matrix is stirred well to obtain desired castings. These castings were studied for behaviour and subjected to mechanical testing to study the effects of various reinforcements. The Rockwell hardness and tensile tests revealed that composite with 7.5 % Al2O3 5% Fly ash shows highest hardness value of 69 HRB and 100.370 N/mm2, which is better than base alloy as well as impact is more without reinforcement ratio shows highest impact strength value 9 joules. Highly reinforced composites show higher variations due to the agglomeration of particles.
