Ductile Fracture Prediction of Stir Casted Al 6061 with B4c and Sic

Abstract

Due to the day by day increased in demands of aluminum in industries like automotive industry and building industry, it is required for improvement of its mechanical properties by addition of suitable alloying elements to aluminum. In this work the ductile fracture of stir casted Aluminum alloy analyzed by the help of various methods. Uses the compositions of three different percentage of Aluminium6061 with Silicon Carbide and Boron Carbide analyzed. This various compositions have been compared with the normal AA6061 based on its tensile test, impact test, hardness test and microstructure analysis. It has been observed that ductile fracture of Al alloys is increasing with the addition of boron carbide (B₄C). The microstructure of the stir casted surface of three various compositions has been analyzed using inverted microscope.
