Abstract
Advance engineering applications demand new generation materials that are stronger, lighter and cheaper that can withstand extreme service loads for higher performance components in aerospace, aircraft and automotive industries. The present study investigates the effect of TiO2 reinforcement to an AA2014. Four aluminum composites samples were developed through multi-step stir casting by reinforcing varying amounts of TiO2 (1.0–4.0 wt.%). The metallurgical characterization was done by optical microscope. The evaluation of tensile properties such as ultimate tensile strength (UTS) and yield strength (YS) was carried out using Vickers hardness and universal testing machine, respectively. The microstructures were correlated to the corresponding mechanical properties. The results revealed that mechanical properties improved constantly with the addition of TiO2. The microstructure of composite samples revealed that the distribution of TiO2 in the matrix is uniform and grain refinement was also observed due to multi-step stir casting.
