The composition of metallic matrix in ductile iron as-cast and after austempering at temperatures of 280, 330 and 380°C (ADI) was examined. The study presents the results of these examinations obtained by Mossbauer spectroscopy. The specimens were taken from cast rods of 60mm diameter. Using calculated values of the parameters of hyperfine interactions (isomeric shift IS, quadrupole splitting QS and hyperfine effective magnetic field H), isolated by deconvolution of the experimental spectrum, the constituents of the metallic matrix were identified in terms of both quantity and quality. The measured values as well as the data compiled in literature indicate that component Z1[...]
