The method of obtaining the vermicular cast iron in the “Inmold” technology and the results of the thermal fatigue investigations, are presented in the paper. The influence of the maximum cycle temperature (Tmax) on the thermal fatigue resistance was examined by means of the L.F. Coffin method. The cast iron structure change caused by the thermal fatigue is presented in the paper. When the vermicular cast iron is subjected to the thermal fatigue the matrix ferritisation occurs, which leads to the strength, Rm., decrease. The heating process of the vermicular cast iron is slower as compared to the spheroidal cast iron, whereas the cooling process is faster. Under the same conditions of heat exchanging the vermicular cast iron is heated to a much lower temperature than the spheroidal one. Together with the maximum heating temperature increase the thermal fatigue resistance decreases.
