Acceleration of Bainitic Transformation in Nanostructured, Low Temperature Bainitic Steels by Using of Thermodynamic Model

Abstract:

Nanostructured, low temperature bainitic steels with remarkable combination of ultimate tensile strength of about 2.5 GPa and high uniform elongation have been developed in the recent decade. To accelerate the bainitic transformation in theses steels, new chemical composition was designed by MUCG83 thermodynamic model which was developed in Cambridge University by Bhadeshia. The samples, prepared from the hot rolled ingots, were transformed isothermally at the temperature range of 200 to 300°C for different times. The microstructure and mechanical properties of the samples were evaluated by XRD, SEM, hardness and tensile tests. The results showed a unique microstructure and good mechanical properties like other bainitic steels, while the needed time for the completion of transformation is shorter compared to that of others.
