Elastic properties of aluminum boron carbide metal matrix composites

Metal matrix composites are being used increasingly for various applications in automotive, aerospace and industrial applications. The present investigation deals with boron carbide used as reinforcement with Aluminum alloy LM6. They offer distinct advantage as they result in a composite with net weight decreasing since density of boron carbide is less compared to aluminum. Since aluminum has better strength to weight ration compared to steel they can be proposed as the candidate material for automotive and especially driveshaft applications. Tension test and Torsion test were carried out according to ASTM E8 and ASTM E143 standards respectively. The weight percentage of reinforcement was chosen up to 7.5 percent. The prepared composite specimen's demonstrated increase in tensile strength, young's modulus, torsional strength and shear modulus up to 6 percent weight percentage of reinforcement. Consequently, there was decrease in percentage of elongation, angle of twist and Poisson's ratio with the incorporation of boron carbide. (C) 2020 Elsevier Ltd. All rights reserved.
