Studying the mechanical properties of aluminum alloy reinforced with graphite and Al2O3 by stir casting process


Mandeep Singh

Aluminum and its alloys are widely used in automobile and aerospace industries due to their excellent mechanical properties, low density, high corrosion resistance and wear and low thermal coefficient of expansion. With these excellent properties and relatively low production cost Aluminum and its alloys have variety of application in scientific and technological viewpoints.rnThe aim involved in present work is to the study of behavior of Aluminum 6063 with Graphite and small quantity of Alumina (AL2O3) composite made by stir casting technique. In this different percentage of reinforcement is used and Density test, Tensile test, Hardness test are performed on the samples obtained from stir casting process. SEM & EDS is also performed on samples to find out the reinforced material.rnTensile test is performed to measure the maximum elongation and reduction in area of metal matrix composites whereas hardness tester is employed to evaluate the bonding between the matrix and reinforced particles with constant load and constant time. SEM and EDS is performed to know the presence of reinforced Alumina particles in the metal matrix composite and elemental composition of samples respectively.
