English abstract:
Advanced bainitic steels exploit their constitution of a phase mixture of bainitic ferrite and retained austenite. The
desired microstructures are usually adjusted via isothermal or continuous cooling treatments below the bainitestart-temperature. In the present work, we analyze the microstructural evolution during bainite formation in
detail and we report on a novel mechanism for the formation of "carbide-free zones" in the close proximity of
austenite. Carbides are formed in the interior of bainitic ferrite, which is isolated from surrounding austenite,
while the depletion of C in the vicinity of austenite suppresses their formation.
