In this study, the bainitic transformation in carbon- and nitrogen-alloyed steels is investigated to understand the influence of carbon (C) and nitrogen (N) on the transformation characteristics and mechanical properties. High-alloyed steel DIN EN X30CrMoN15-1 is subjected to detailed analysis using quenching dilatometry for isothermal heat treatments, which allows for the concurrent acquisition of transformation behavior data. Scanning electron microscopy (SEM) and electron backscatter diffraction (EBSD) reveal the formation of bainitic microstructures with retained austenite post heat treatments lasting 24 hours. The results indicate that annealing temperatures between 200 °C and 176 °C produce nanoscale plate-like bainite structures characterized by plate widths below 40 nanometers, achieving a hardness exceeding 600 HV10. Wavelength dispersive X-ray spectroscopy (WDS) confirms that nitrogen diffusion behavior during bainite formation is comparable to that of carbon, while transmission electron microscopy (TEM) studies further elucidate the nanoscale microstructure, showcasing Fe2C and Cr2N precipitates. This comprehensive examination enhances our understanding of the complex interactions in C + N alloyed steels.
