Özet
In this study, the effects of the oxide films formed by using different mold cavity geometries on the mechanical properties of the parts were investigated. The casting process was carried out using the same runner system with different mold geometries. The effect of liquid metal flow rate on bifilm formation and the mechanical properties of the cast material were examined. Eventually, oxide bifilms formed in the mold cavity when the flow rate is low (caused by folding). These oxide bifilms negatively affect the mechanical properties as much as the oxide bifilms formed in the runner system. When real-time liquid metal flow rates are examined in different casting cavities, flow irregularities such as turbulence, folding, and splashing were developed differently in the flow rate of the liquid metal. It was determined that the stability in the flow rate of the liquid metal directly affects the mechanical strength.
