Experimental mechanical properties and corrosion resistance on A16061 reinforced with Fe2 O3 and B4 C hybrid composites

Abstract

Recently, the utilizations of Metal Matrix Composites are expanded in science, engineering and technology applications. In view of their unique properties such as mechanical, physical, wear resistance and corrosion behavior compared with other Metal Matrix Composites (MMC), Aluminum Matrix Composites (AMC) has some unique characters such as high thermal conductivity, high stiffness, high strength, and low weight ratio. In this way, AMCs are the better substitution of regular materials in Automotive components, Aerospace, Electrical fittings, and other Modern applications. In AMCs, there are many reinforcements such as Titanium carbide, Silicon carbide, Aluminium oxide, and Aluminium Nitride, etc., which have been used in past decades and the stir casting method is commonly used because of low cost and very effective production technique. In this research stir casting method is utilized for producing Al6061 composites with different weight percentages (Wt.%) of reinforcements. The modifications of Al6061-T6 metal matrix composites are an extraordinary enthusiasm of recent pertinence for lesser weight materials with the high value of tensile strength, hardness and wear protection, which can be widely used in automotive and aircraft design. In this research shown the impacts of the reinforced Al6061 composite with 5 wt. % of Fe2O3 in addition to 2%, 4%, 6% weight of B4C being made-up by stir casting technique. In this research, Al6061 composites have analyzed by its physical and mechanical properties like as density, hardness, impact, ultimate tensile, and compressive strength, as per the ASTM standards and an optical microscope is utilized to assess the metallurgical properties such as microstructure with different wt. % of reinforcements of Al6061 composites. The microstructure of newly prepared composites was shown a regular spreading of reinforcements in the matrix by an optical microscope and also the muscular bonding between the matrix and reinforcements is demonstrated by SEM analysis. newline
