Bainite morphology in experimental FE-MO-CR-V-TI-C steel

The development of bainitic transformation was studied using TEM, dilatometry and thermodynamic calculations, both from a fully austenitic microstructure (TA=1200oC) and from a microstructure containing a mixture of austenite and undissolved carbides (TA=1000oC). The amount, distribution and morphology of retained austenite, bainitic ferrite and precipitation of carbides strongly depends on both; prior austenitization and isothermal transformation temperatures within the bainitic range.
