6. Cantor-Alloy-Based Multicomponent Nitride Thin Films
Sammanfattning : In this Thesis, I have investigated multicomponent alloy based thin films synthesized by magnetron sputtering. The studies in the thesis are centered around the phase diagram of the CrFeCoNi nitrogen containing system. LÄS MER
7. On the hot crack formation during solidification of iron-base alloys
Sammanfattning : Hot cracking during solidification is a severe problem inmany casting processes, for example in continuous casting.Combinations of low strength and low ductility of the materialat high temperatures and applied tensile stress can cause hotcracking. LÄS MER
8. Theoretical Descriptions of Complex Magnetism in Transition Metals and Their Alloys
Sammanfattning : In this thesis, various methods for studying solids by simulations of quantummechanical equations, have been applied to transition metals and their alloys. Transition metals such as Fe, Ni, and Mn, are not only cornerstones in modern technology, but also key components in the very fabric of the Earth interior. LÄS MER
9. Influence of stresses and impurities on thermodynamic and elastic properties of metals and alloys from ab initio theory
Sammanfattning : Stresses and impurities may influence elastic properties, phase stability and magnetic behavior of metals and their alloys. A physical understanding of this influence is of great importance to both fundamental science and technological applications. LÄS MER
10. Thermodynamic and Kinetic Investigation of the Fe-Cr-Ni System Driven by Engineering Applications
Sammanfattning : This work is a thermodynamic and kinetic study of the Fe-Cr-Ni system as the core of stainless steels. The Fe-Cr, Fe-Ni and Cr-Ni systems were studied intensively using both computational and experimental techniques, including CALPHAD (CALculation of PHAse Diagrams), phase field simulation, ab initio modeling, calorimetry, and atom probe tomography.
