Post inoculation in the structural control of ductile cast iron

Abstract

Ductile Cast Iron, a relatively new engineering material has been the subject of intensive investigations in recent years. It is essential to have an improved understanding of the mechanism of nodule formation, economical methods of processing and mechanical properties of commercial ductile cast irons. The present study deals with the beneficial effects of Post-Inoculation on the as-cast structure and properties of ductile iron. Post-inoculation process was carried out on ductile iron melts and tensile test, charpy impact test, chemical composition and microstructure analysis were performed for evaluation.
