The first part of this study describes the methods of obtaining a bainitic structure in ferrous alloys. The TTT diagrams were characterised along with the run of cooling curves for ductile iron in its alloyed, unalloyed and low-alloyed variations. Next, the effect of alloying additions on the hardenability of ferrous alloys was discussed. A formula was given to determine the temperature of the beginning of bainitic transformation with examples of the diagrams illustrating the effect of some selected alloying additions on the hardenability factor. Special attention was paid to a complex role played by boron and vanadium.
