Thermal analysis (TA) of modified gray cast iron (GCI) and vermicular graphite cast iron (VGCI) treated by foreign and domestic graphitizing and spheroidizing modifiers is conducted on a TA device using data processing software. Cooling curves (current temperature measured in solidification time, T–t) and the derivatives of the cooling curves (temperature change rates vs. the solidification time, dT/dt–t) have been constructed under the AO AVTOVAZ iron foundry conditions.
