1. Thermodynamic modelling and assessment of some alumino-silicate systems
Sammanfattning : Alumino-silicate systems are of great interest for materials scientists and geochemists. Thermodynamic knowledge of these systems is useful in steel and ceramic industries, and for understanding geochemical processes. A popular and efficient approach used to obtain a self-consistent thermodynamic dataset is called CALPHAD. LÄS MER
2. Thermodynamic Database for Zirconium Alloys
Sammanfattning : For many decades zirconium alloys have been commonly used in the nuclear power industry as fuel cladding material. Besides their good corrosion resistance and acceptable mechanical properties the main reason for using these alloys is the low neutron absorption. LÄS MER
3. Thermodynamic description of the Fe-C-Cr-Mn-Ni-O system
Sammanfattning : The Fe-C-Cr-Mn-Ni-O system is of fundamental importance when describing the influence of oxygen on high alloyed steels. Both solid and liquid phases are of great interest: The solid phases regarding oxidation processes like the formation of oxide layers, inner oxidation, sintering processes and high temperature corrosion.

4. Studies of Steel/Slag Equilibria using Computational Thermodynamics
Sammanfattning : The main focus in the present work concerns calculations on steel/slag equilibria. Thermodynamic software and databases are now powerful and accurate enough to give reliable results when applied to complex metallurgical processes. One example is the decarburization process of high alloyed steels. LÄS MER
5. Thermodynamic study of the FeO-MgO-Al2O3-SiO2 system : Data assessment and phase diagram calculation
Sammanfattning : This dissertation consists of assessed thermodynamic properties for phases in the geologically and industrially important system Fe-Mg-Al-Si-O and calculated phase diagrams. Mathematical processing of different kinds of experimental data (phase equilibrium data, calorimetric, volumetric, thermophysical,electrochemical, activity data) is used to derive internally consistent thermodynamic database.
