	abstract="{The influenceof  a  shape  of  graphite  precipitates  in  cast  iron on  the  thermal  shock  resistance  of  the  alloy  was  initially  determined. Investigations included the nodularcast ironand the vermicular one, as well as the cast iron containing flake graphite. The thermal shock resistance  was examined at aspecial laboratory stand which allowed for multiple heating and cooling of specimens  within the presumed temperature range. The specimens were inductively heated and then cooled in water of constant temperature of about 30°C.Therewere used flat specimens 70 mm long,5 mm thickin the middle part, and tapering like a wedgeover a distance of 15 mm towardsboth ends. The  total  length  of  cracks generated  on  the  test  surfaces  of  the  wedge-shaped  parts of  specimens  was measuredas  a  characteristic  value inversely proportional tothe thermalshock resistanceof a material.The specimens heated up to 500°C were subjected to 2000 test cycles of  alternate  heating  and  cooling, while the specimens heated up to 600°C underwent 1000 such cycles. It was found that as the heating temperature  rose  within  the  500-600°C range, the thermal shock resistance decreased for all examined types  of  cast  iron.  The  research study  proved  that  the  nodular  cast  iron  exhibited  the best  thermal  shock  resistance,  the  vermicular cast  iron  got  somewhat  lower  results, while the lowest thermal shock resistance was exhibited by grey cast iron containing flake graphite.}",
