The study presents the results of impact tests carried out on austenitic ductile iron with 30% Ni. The examined material was subjected to dynamic loads within a wide range of temperatures from (-196°C) to (+400°C). The fractures were examined under a JEOL JSM 6460LV scanning electron microscope. Additionally, microstructural examinations were carried out and chemical analysis in microregions was done by EDS.
