Abstract
Gas entrapment and porosities are the two common drawbacks associated with gravity die process. In this study, the effect of gravity die different pouring temperatures at 680, 710, 740, and 780 on die casting material particularly AZ91D mechanical properties namely; tensile strength, yield strength, elongation percentage, and porosity percentage were investigated. The result showed that higher strength was obtained at lower pouring temperature. The highest porosity percentage was observed at the areas nearer to the riser, and lower porosity percentage was obtained nearer the ingate. The highest tensile strength, yield strength, percentage of elongation and less percentage of porosity was obtained for the specimens taken nearer to the ingate which is the starting point of melt entry into the cavity.
