Abstract
Studies have been made on the influence of water and air cooling coupled with inoculation on the mechanical properties of 6063 aluminum alloy. The work was aimed at investigating the combined effects of two crystallization enhancers in order to provide a synergy-form of effect in the mechanical properties using 4.2% wt and 16.5% wt Ni powder particles. The alloying compositions, phase change and micro-hardness were determined by using energy dispersive spectroscopy (EDX), XRD and Brinell microhardness tester. The surface morphology of the alloyed sample using scanning electron microscopy (SEM) showed that Ni particles were distributed by virtue of surfactant addition and mechanical stirring. Addition of Ni powder coupled with increase in solidification rate yield size reduction in aluminum alloy structure. The results also revealed that conglomeration of inoculant addition and water cooling increased the fracture strength of the aluminum alloy while both axial and lateral deformations were altered.
