Literature Review of Microstructure Formation in Compacted Graphite Iron

• The literature concerning microstructure formation in Compacted Graphite Iron (CGI) is reviewed. CGI has an intermediate graphite morphology between Lamellar Graphite Iron (LGI) and Spheroidal Graphite Iron (SGI). The formation of compacted graphite morphology is controlled by small changes in alloy composition. Several important factors influencing the formation of the as-solidified microstructure, as well as the microstructure formation during the eutectoid transformation are also reviewed. The focus of this review is to compare mechanisms in which CGI differs from LGI and SGI. The effects of microstructure on some properties that are relevant in commercial applications are included in the study. Additionally the relatively few models for microstructure formation are also summarised.
