Abstract
Bainitic reaction kinetics in ductile iron contained according to Ukrainian standard (weight %) 3.60-3.80 carbon, 2.60-2.80 Si, - 0.12 Mn, - 0.60 Cu and additionally alloyed by Mo (0.150-0.20) has been studied. It was found that the overall transformation kinetics becomes slower as transformation temperature increase. This is because more intensive redistribution of carbon into austenite at higher temperatures. Two austenites wiith different carbon content have been fixed and kinetics of their lattices parameters has been studied.
