    Eutectic transformation in ductile cast iron. Part I - Theoretical background
    (2005) Fraś, Edward; Górny, Marcin; López, Hugo F.
    In the present paper, heat balance is incorporated in developing expressions for the solidiflcation kinetics of divorced eutectic in ductile cast iron taking into account nucleation and growth processes for spheroidal graphite. Accordingly, a new analytical equations were derived that describe the nodule count N and the chill and chilling tendency CT of ductile cast iron. From this analysis, it is viable to predict cast nodule counts as well as the chill and CT for ductile iron from experimental data on cooling rates, chemical composition and other factors. Finally, the effect of technological factors on the resultant nodule counts the chill and chilling tendency is considered in this work.
