Enhancement of mechanical characterization of aluminum alloy with tungsten carbide metal matrix composite by particulate reinforcements

Abstract

Composite materials exhibiting good ductility and tensile strength are preferred for a wide array of applications that ranges from building components, automobiles, and aircraft. Aluminum alloy matrix and tungsten carbide reinforcements provide required properties that enhance the mechanical properties of the composites. In this study, the ductility and Young’s modulus of four composites consisting of 1%, 2%, 3%, and 4% wt. of tungsten carbide particulates were compared with that of base metal AA6061. From the experimental investigations, it was found that the improvement of ultimate tensile strength, hardness, and also Young's modulus and accompanied by a reduction of ductility was directly proportional with an improvement of Tungsten carbide particle content.
