For an industrial melt of ductile cast iron, the effect of the rate of cooling after austenitization at temperature 900°C carried out for 30 minutes on temperatures TAr1 start and TAr1 end was determined. The heating rates applied in the study were the same as the cooling rates and equaled 30, 60, 90, 150, and 300°C/h. It has been found that with increasing cooling rate, values of temperatures TAr1 start and TAr1 end decrease by several dozen degrees.}, type={Artykuły / Articles}, title={Determination of Eutectoid Transformation Temperatures in Ductile Cast Iron}, URL={http://journals.pan.pl/Content/88836/PDF/10_paper.pdf}, doi={10.1515/afe-2015-0078}, keywords={Ductile cast iron, Eutectoid transformation, Cooling rate}, }
