Abstract [en]

Thermodynamic descriptions of the Fe-Mg-O, Fe-Ca-S and Fe-Mg-S systems are all important in order to perform thermodynamic calculations related to the steelmaking process. The experimental information of many sulphur-containing systems, including Fe-Ca-S and Fe-Mg-S, is lacking and they are here thus approximated to behave similarly to the corresponding oxygen systems. This study presents a description of the Fe-Mg-O system in good agreement with experimental information. Additionally, descriptions of the Fe-Ca-S and Fe-Mg-S systems are presented. These descriptions may be reasonable estimations considering the lack of experimental information.

Abstract [en]

The thesis starts by giving a motivation to materials modeling as a way to increase profitability but also a possibility decrease the environmental impact. Fundamental concepts of relevance for this work are introduced, this include the materials genome, ICME and of course the CALPHAD method. As a demonstration promising results obtained by an ICME approach using genetic algorithms and CALPHAD on the vacuum degassing process are presented. In order to make good predictive calculations and process models it is important to have good thermodynamic descriptions. Thus most part of the work has concerned the thermodynamic assessments of systems of importance for steelmaking, corrosion and similar processes. The main focus has been the assessment of sulfur-containing systems and thermodynamic descriptions of the Fe-Mn-Ca-Mg-S, Fe-Ca-O-S, Fe-Mg-O and Mg-Mn-O systems are presented. In addition, heat capacity measurements of relevance for the Mg-Mn-O system have been performed. To summarize the efforts some application examples concerning thermodynamic calculations related to steelmaking and inclusion formation are shown.
