Resumen:
The
mathematical model of the globular eutectic solidification in 2D was designed. Proposed
model is based on the Cellular Automaton Finite Differences (CA-FD) calculation
method.
Model
has been used for studies of the primary and of globular eutectic grains growth
during the ductile iron (DI) solidification. A hyper-eutectic composition has
been analyzed but this model can be used in the solidification modeling of
hypo- and eutectic DI. The proposed model makes possible to trace the
unrestricted growth of primary grains of two phases from the liquid, transition
from free to cooperative solidification, and cooperative growth of globular
eutectic.
