WebFeb 21, 2011 · Graphite morphology in cast iron is analyzed in terms of the growth kinetics of graphite crystals in liquid iron. At small driving forces, i.e., low supersaturation or small kinetic undercooling, graphite growth is characterized by faceted growth, resulting in flake, compacted and spherulitic graphite morphologies. WebOnce the graphite flake has formed, its shape cannot be changed later by any method. Fig. 15.1 (b) illustrates the effect of carbon and silicon on the structure of white or grey cast irons. ... Cast iron in general are never water-quenched (except in surface-hardening) as it has relatively high hardenability to get martensite by oil-quenching ...
