Evaluation of Mechanical Properties of Al7075 MMCs Reinforced With Nano Silicon Carbide (SiC), and Nano Aluminium Oxide (Al2O3)

The main object of this paper to study the mechanical properties and wear characters of Al7075 MMCs reinforced with Nano SiC, and nano Aluminium oxide Al2O3.The reinforcement is varied in 2 sets. In 1st set SiC(0.1%) is kept constant for 3specimens and Al203 (0.1%,0.2%,0.3% )is varied, and in 2nd set SiC(0.2%) is kept constant for 3specimens and Al2O3(0.1%,0.2%,0.3%) is varied respectively. This process is carried out by stir casting process, after casting mechanical properties can be tested by tensile test, Impact test and wear test. Aluminum alloys are preferred and widely used in engineering material for making components in aerospace, automobile because the composite which is formed out by casting are of having high wear resistance, stiffness, and good strength. The result shows that there is gradually increase in wear resistance readings by maintaining SiC weight percentage constantly and varying Al2O3
