Führer, M., Zamberger, S., & Povoden-Karadeniz, E. (2025). Experimental determination of AlN in microalloyed steel and thermodynamic analysis. CALPHAD-COMPUTER COUPLING OF PHASE DIAGRAMS AND THERMOCHEMISTRY, 88, Article 102790. https://doi.org/10.1016/j.calphad.2024.102790
Differential Scanning Calorimetry measurements are performed with a subsequent postprocessing routine specially designed for dilute systems, aiming at the evaluation of the solvus temperature of AlN in seven microalloyed steel laboratory melts. Computer-aided EDS particle analysis of the steel microstructure confirms the DSC results. With this consistent set of new data directly related to observed AlN stability, coupled with critically assessed thermodynamic data from the literature, the thermodynamic description of the AlN phase is reconsidered.
