Proportion of diffused eutectic graphite during solidification of cast iron. The following interdependencies shall apply according to Eq. 1 and Eq. 2:
Eq. 1
and
Eq. 2
Sc = degree of saturation
Since this type of graphite diffusion causes an increase in volume, cavity formation (s. Cavities) is reduced with increased diffusion of eutectic graphite.
