    To quantify the way in which microstructure, stress, and distortion develop during the cooling of a ductile cast iron GJS-600 after its solidification and to predict the final thermomechanical properties of this material, it is necessary to identify all the metallurgical evolutions in solid state which occur after the casting in a sand mold. The present work deals with the influence of cooling conditions on the solid state transformations of a ductile cast iron austenitized for short periods and considering the initial carbon gradient. Numerical predictions for the modeling of the microstructure evolution and for the thermal strain development are validated with experimental results and show good agreement.
