Phase Transformations and Complex Properties - Cast Irons

Cast Irons Miguel Angel Yescas-Gonzalez and H. K. D. H. Bhadeshia Cast irons typically contain 2-4 wt% of carbon with a high silicon concentrations and a greater concentration of impurities than steels. The carbon equivalent (CE) of a cast iron helps to distinguish the grey irons which cool into a microstructure containing graphite and and the white irons where the carbon is present mainly as
