Effect of process parameter on synthesizing of TiC reinforced Al7075 aluminium alloy nano composites

Abstract In the present study TiC of differing its weight percentage (3%wt, 6 wt%, and 9 wt%) reinforced Al7075 aluminum alloy is synthesized by adopting stir casting method. However, achieving a consistent distribution of reinforcement of nanoparticles in the matrix alloy is more significant. Hence it is essential to explore the process parameters to achieve the uniform distribution of reinforcement in the matrix alloy such as stirring speed, stirring time, and by this, the influence of the mechanical property of aluminium alloy matrix composites has to be characterized. It has been observed that by increasing such parameters it resulted in better distribution of reinforcement particles in the synthesized composites, owing to that it enhances the microstructure and mechanical properties of composites such as the compressive strength increased to 232 Mpa, at stirring speed of 600 rpm and stirring time is maintained at 15 min. At this value, it is inferred that the TiC particles are consistently dispersed in the matrix alloy with an interfacial phase of AlTi2.
