Abstract
Based on the classic diffusion controlled nucleation and growth theory, the sympathetic nucleation-ledgewise growth mechanism of bainite was studied t heoretically for low carbon F-e-C alloys. The rationality of the occurrence of sympathetic nucleation on the terraces of ledges competing with lateral ledge growth and other sites nucleation was demonstrated by the present wo rk quantitatively. The calculations indicated that low reaction temperature s and high carbon concentrations may favor the sympathetic nucleation, thus accounting for the formation of multilayer structures of bainite.
