摘要

This research study evaluates the functional properties of an aluminium alloy (Al6061) composite incorporating 3 wt% titanium carbide (TiC) and varying wt% alumina (Al2O3) nanoparticles via a vacuum-aided stir-cast production technique. During the composite production, calcium (Ca) and argon gas are used to enhance the wettability and limit oxide formation. The combined effect of composite processing and hybrid reinforcements on microstructure and mechanical properties of the composites was investigated by an ASTM standard. The results showed that the nanoparticles were strongly dispersed in the base matrix, and the constant stir speed led to even particle distribution. The applied vacuum pressure reduces the porosity to less than 1 %. Moreover, the composite sample of 3 wt% TiCl6 wt% Al2O3 is observed to have an improved energy absorption of 25.5 J/cm2, a higher Vickers hardness number of 134 HV, and an optimum yield, ultimate tensile strength of 301 and 362 MPa.
