The final mechanical properties of cast iron depend on the nature and properties of the matrix and on the morphology of graphite precipitates. The article presents the results of studies of the structure of austenitic ductile iron with different nickel content. The studies include the identification and stereological description of graphite precipitates. The volume fraction of graphite in cast iron was determined in function of the size of the precipitates and the adopted shape coefficient of single particles, enabling the content of regular spheroids to be estimated.
