In the present work the temperature intervals of phase transitions in the matrix of ductile and mottled irons and overall kinetics of bainite reaction were studied by dilatometrical method. These data were summarized in the form of time-temperature transformation (TTT) diagrams for both cast irons. It has been found that there are two C-shape curves corresponding to formation of upper and lower bainities in the studied ductile iron. This could be interpreted as a result of individual dependencies of nucleation and growth rates of upper and lower bainitic alpha-phases due to realisation of different crystalographic shear systems during transition. The phenomena is not so evident in the case of mottled iron probably due to more complicate segregation pattern in the matrix as a result of realisation of both metastable and stable eutectic reactions during solidification.
