Experimental determination of AlN in microalloyed steel and thermodynamic analysis
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.
期刊介绍：
The design of industrial processes requires reliable thermodynamic data. CALPHAD (Computer Coupling of Phase Diagrams and Thermochemistry) aims to promote computational thermodynamics through development of models to represent thermodynamic properties for various phases which permit prediction of properties of multicomponent systems from those of binary and ternary subsystems, critical assessment of data and their incorporation into self-consistent databases, development of software to optimize and derive thermodynamic parameters and the development and use of databanks for calculations to improve understanding of various industrial and technological processes. This work is disseminated through the CALPHAD journal and its annual conference.
