Influence of Nano TiO 2 Particles on the Properties and Behaviour of A356 Aluminium Metal Matrix Composites 2017-28-1986

In this study, the TiO2 nano particles are incorporated with A356 aluminium to form a Metal Matrix Composite (MMC) to be utilized in aerospace, marine, military and automotive applications. Stir casting method was used for producing the metal matrix composites. A356 aluminium was reinforced with various weight percentage (wt%) of TiO2 under 10 minutes holding time and 450 rpm stirring speed. Mechanical properties such as tensile strength and hardness of the Metal Matrix Composite were tested. Using Scanning electron microscope the surface morphology and composition of the manufactured specimens were studied. Energy dispersive spectroscopic analysis was carried out to study the elemental composition of the MMC. The mechanical tests reveal that there is a significant enhancement in the properties of the composites with 1.5 wt% of TiO2.
