A review on change in mechanical properties of aluminum metal matrix composite by different reinforced particles
Mandeep Singh, Arvinder Singh Channi
Aluminum and its alloys are broadly 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 applications in scientific and technological viewpoints. The aim involved in present paper is to the study of behavior of Aluminum with different reinforced particles like Graphite, Alumina (Al2O3), SiC, fly ash, etc composites made by stir casting technique. In order to perform these tests reinforcement of different percentage is used and tests like Hardness, toughness, impact, Density and Tensile test are performed on the samples prepared by using stircasting technique Tensile test is performed to measure the maximum elongation and reduction in area of metal matrix composites where as hardness tester is employed to evaluate the bonding between the matrix and reinforced particles with constant load and constant time. SEM XRD and EDS is performed to know the presence of reinforced Alumina particles in the metal matrix composite and elemental composition of samples respectively. The outline of the fabrication indicates that the method is relatively successful as the results clearly shows that on increasing the weight percentage of reinforcement there is an increase in hardness and tensile strength.
