Effect of Addition of Nanoparticles on the Mechanical Properties of Aluminium

Abstract

Aluminium matrix nanocomposites (AMNC) have a wider application area because of their low density and high specific stiffness. This experimental investigation was conducted to fabricate aluminium matrix nanocomposite samples using TiO2 nanoparticles as the reinforcement by using powered stir casting method. The mechanical properties such as tensile strength and hardness are determined and compared with that of Aluminium. Microstructural characterization and X-ray diffraction studies were conducted on these prepared nanocomposite samples. The study reveals that the presence of TiO2 nanoparticles in the aluminium matrix led to a significant improvement in the mechanical properties of the prepared nanocomposite samples when compared with that of the commercially pure aluminum. Microstructural evaluation and X-ray diffraction studies showed a positive response to the addition of TiO2 nanoparticles into the aluminium matrix.
