Effect of ceramic reinforcement on mechanical properties of aluminum matrix composites produced by stir casting process

The effect of ceramic reinforcements as Al2O3 on the mechanical properties of Al-7072 for different weight fraction manufactured using the stir casting technique is studied. Mechanical properties such as tensile strength, Young's modulus, ductility, compressive strength, hardness and impact resistance were evaluated for both samples Al-reinforced and unreinforced 7072. The results show that as the content of reinforcing particles increased, there was significant increase in mechanical properties such as breaking strength and compressive strength, hardness and ductility followed by a reduction in density. There has also been an attempt to reveal the microstructure study of samples using light microscopy. The microphotographs of the samples indicate the uniform Al2O3 particles in the matrix distribution. (C) 2017 Elsevier Ltd. All rights reserved.
