Experimental analysis and characterization of Mechanical, Physical properties of Aluminium (Al6061) Metal Matrix composite reinforced with SiC and Al2O3 using Stir casting

Abstract

Metal matrix is defined as two or more material mixing with each other, In these constituents, one is mainly metal and the other is non-metals such as ceramics, glass and rubber etc. There is a wide scope for metal matrix composites nowadays. Among various metal matrix composites, Aluminium MMC yields good results, when compared with other MMC (metal matrix composite These reinforcements have much higher strength and wear resistance than pure aluminium. Multiple reinforcements in an aluminium metal matrix composite have a lot of potential. The use of metal matrix composites with Al6061 as parent material and infusion of reinforcements like Carbides, Oxides and Borides have resulted in materials with improved mechanical strength and usability. This paper contains the investigation of Mechanical Properties of Aluminium 6061 and Aluminium 6061 reinforced with SiC, Al2O3 particles. In this, we are focusing Al MMC by undergoing various tests such as impact, hardness and tensile tests. In the present work, aluminium matrix hybrid composite of Al6061+ X wt% of Al2O3 + Y wt% of SiC (X = 2.5,5 % and Y = 5,2.5%) was successfully fabricated by stir casting method. The effect of Al2O3 and SiC reinforced in the matrix were investigated through tensile test, impact test, hardness values and SEM analysis (for Morphological characteristics) and the best composition of AMMC matrix was determined.
