Can slow cooling of nodular cast iron segregate into graphite balls and low carbon steel?How Mg or Ce reduce surface tension of molten graphite?

30 December 2019 0 907 Report

graphite is less dense than molten iron, and steel has higher melting point than cast iron. is the way asked in question can provide satisfactory segregation? if yes, then how? (alloying and heat treatment methods). If no. then why not? high C-Fe attraction?
