Effect of Section Thickness on Solidification and Microstructure of Ductile Cast Iron

In the current situation, where the energy crisis is continuously worsening, industries and researchers are vigorously working toward a common energy savings objective through various techniques. The usage of lightweight components is increasingly prioritized by manufacturing sectors to reduce total energy consumption. Ductile cast iron is one of the leading alloys in structural and automotive applications. The solidification of ductile iron castings with both thick and thin walls has drawn more attention in recent years. However, it is challenging to produce thin-walled ductile cast iron items due to their intricacy. The morphology of the cooling curves and the microstructure of variable thickness (both thick and thin) ductile iron casting are explored in this study. According to the findings of the solidification and cooling curve study of the variable thickness step casting, thick portions show a prolonged eutectic reaction compared to the thin portion of step casting.
