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 selected was Aluminium 7029 and it is reinforced with varying volume percentage of Zirconium dioxide & Graphite. These AMMC were developed by using crucible casting technique, in which predetermined reinforcement is added to the molten matrix is stirred well to obtain desired castings. The Rockwell hardness test revealed that AL85%, Zro215 % & Graphite 5% composite shows highest hardness value of HRB – 61, Impact shows that AL80%, ZrO2 10% & Graphite 10% composite has highest value - 11 Joules/mm2 & highest tensile strength - 113.90 N/mm2. Highly reinforced composites show higher hardness and Lower percentage of reinforcement has high tensile strength and Moderate reinforcement shows high impact strength variations due to the agglomeration of particles.
