Synthesis and Evaluation of Mechanical properties of Al/ Sic Composite by Stir Casting Method (original) (raw)

The main focus for this project is to find out the betterproportion of the AA6061 – Sic composite by analyzing their mechanical properties which has been made by stir casting method.The Mechanical properties of AA6061 Aluminium matrix composites (AMC's) when reinforced with Sic with varying weight percentages that can be used for high performance applications such as automotive ,aerospace, military and electrical industries has been evaluatedStir casting has been used to synthesize Al/Sic MMCs by reinforcing silicon carbide particles into aluminum matrix. The reason for using stir casting is to develop technology for the development of MMCs at affordable cost. The selection of Sic as reinforcement and Al as matrix isbecause of their easy availability. The practical data acquired, analyzed and optimized will beinterpreted in the light of information available in the literature and be shared with the relevant industries. The present work was mainly carried out to characterize the Sic/Al composite which was produced by reinforcing the various proportions of Sic (5, 10, and 15%) in aluminum matrix using stir casting technique. Itis noted that the volume fraction of Sic in the composite is gradually increased, the hardness and impact energy increase. However, beyond a level of 25-30 percent Sic, the results are not very consistent, and depend largely on the uniformity of distribution of Sic in the aluminum matrix.This work is focused to study the change in behavior of AA6061 aluminum alloy by adding different percentage of Sic Then tensile tests, hardness test, impact test performed on these samples which are produced by stir casting to investigatethe improved physical and mechanical properties.
