Abstract

AbstractCompacted graphite iron (CGI) is one among the highly unrated material which has the potential to bridge the application gap persist using Flake graphite iron (FGI) and Spheroidal graphite iron (SGI); especially for high pressure and greater thermal loading boundary conditions. CGI microstructure comprises dense and interconnected worm/vermicular shaped graphite morphology which forms during the graphite transition from flake to sphere form or vice versa while the development of FGI and SGI. Such distinct microstructure offers intermittent mechanical and physical properties as compared to FGI & SGI, which makes CGI a unique proposition to address the industrial challenges for reliable product designing at minimal cost implication for automobile application. However, there are certain known challenges for CGI mass production due to worm graphite morphology sensitivity to foundry recipe and production approach. The worm graphite transformation stabilizes during the narrow window of flake to sphere graphite transition using the shape controlling elements so that it needs highly controlled foundry processes to bring the success for reliable mass production. Hereby, it is attempted to bring insight regarding CGI material microstructure, chemical composition, characteristics, and its technology evolution for mass production.KeywordsCGICG ironCompacted graphite ironVermicular graphite iron
