6. 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.

7. Thermodynamic Modelling and Performance of Combined Solid Oxide Fuel Cell and Gas Turbine Systems
Sammanfattning : Solid oxide fuel cells (SOFCs) are a ceramic type of fuel cell operating at elevated temperatures. By utilising the thermal energy from the SOFC in a heat engine, a hybrid cycle with high performance can be achieved. One promising concept is a pressurised SOFC in combination with a recuperated gas turbine cycle. LÄS MER
8. Oxidation and Corrosion of New MCrAlX Coatings : Modelling and Experiments
Sammanfattning : MCrAlY coatings (“M” for Ni and/or Co) are widely used for the protection of superalloy components operated at high temperatures such as in the hot sections of gas turbines. The exposure to high temperature can cause coating degradation due to oxidation or hot corrosion at the coating surface. LÄS MER
9. Modelling mechanical properties by analysing datasets of commercial alloys
Sammanfattning : Commercial alloys are continuously developed to improve their performance. Therefore it is important to develop new optimisation software, which could be used in development of new materials or in materials selection. In this study the mechanical properties which are important in materials selection in mechanical design are investigated. LÄS MER
10. 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
