Eutectic graphite quantity

Proportion of diffused eutectic graphite during solidification of cast iron. The following interdependencies shall apply according to Eq. 1 and Eq. 2:

Eq. 1


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.
