Influence of nano titanium oxide reinforced Al-7075 matrix composites in stir casting method

Abstract

Aluminium-based alloys have garnered a lot of attention as lightweight materials due to their outstanding mechanical qualities, good castability, and dimensional stability; they withstand damping capacity and abundance as a natural based mineral. The microstructural and interfacial properties of nano TiO2 can significantly impact the mechanical behaviour of Aluminium Matrix Composites (AMCs). The primary goal of this investigation is to extend novel creation of nanocomposite materials with an advantageous arrangement of thermal analysis, mechanical performances, oxidation process, and other mechanical characteristics. The samples were created using the conventional stir casting with aluminum-nano TiO2 composites. The interfaces were investigated using tensile, elongation, Vicker's hardness and scanning electron microscopy to understand the microstructural and interfacial evolution between Al 7075/nanoTiO2 matrix. The microstructural characterization of the nano based TiO2 reinforcing phases in the Aluminium matrix reveals a rather unvarying dispersion of the reinforcing phases. Compared to the parent material, the prepared composite exhibited a notable enhancement in hardness strength, elongation, and ultimate tensile strength.
