THE INFLUENCE OF TiO2 NANOPARTICLES ON THE MECHANICAL PROPERTIES AND MICROSTRUCTURE OF AA2024 ALUMINIUM ALLOY
Keywords:
metal-matrix composites, nanoparticles, aluminum matrix, aging
Abstract
In this study aluminum alloy 2024 was reinforced with different mass fractions (0 w/%, 2.5 w/%, 5 w/%, and 7.5 w/%) of titanium dioxide nanoparticles using the stir-casting method. The main objective was to study an effect of an addition of TiO2 nanoparticles on the microstructure and the mechanical properties of the 2024 aluminum alloy composite fabricated by stir casting. Scanning electron microscopy, energy-dispersive analysis, as well as X-ray diffraction analysis were implemented to characterize the microstructure, elemental and phase composition of the samples. The tensile and Vickers hardness tests were carried out to evaluate the mechanical properties. The results showed that the addition of 7.5 w/% TiO2 nanoparticles increases the ultimate tensile strength by 37 % and elongation by 71 % while decreases the hardness by 14 % comparing with the initial alloy. The highest hardness was demonstrated in the alloy with 5 w/% TiO2.
