1. 1. Multiscale Modeling of Interfaces

   Författare :Sven Johansson; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; misfit; Peierls-Nabarro model; semicoherent interfaces; interfaces; cemented carbides; grain boundaries; microstructure; VN precipitates; density-functional theory;

   Sammanfattning : Understanding strength and stability of interfaces between dissimilar materials or phases is a highly active field of contemporary materials research. Knowledge of interface structure and energetics is important for modeling of complex materials both on a mechanical and thermodynamical level as well as for many functional properties. LÄS MER

3. 2. The Europeanisation  of gender equality : The unexpected case of Sweden

   Författare :Tanja Olsson Blandy; Christina Bergqvist; Ann-Cathrine Jungar; Helena Stensöta Olofsdotter; Uppsala universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; gender equality; Europeanisation; state feminism; framing; norm entrepreneurs; actors’ strategies; equality agencies; JämO; femocrats; misfit; domestic change.; Political science; Statsvetenskap;

   Sammanfattning : The main objective of this thesis is to analyse how the Swedish Equal Op-portunities Ombudsman (JämO) has used EU legislation as an opportunity for influencing the domestic policy process. Prior to Sweden’s membership in the EU, few pay-discrimination cases had been referred to the Labour Court, and none by JämO. LÄS MER

4. 3. Toward first-principles understanding of carbonitride precipitation in steels

   Författare :Dan Fors; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Steels; Coarsening; Interfaces; Peierls-Nabarro model; Diffusion; Precipitates; Density functional theory; Dislocation network; Misfit; Electronic structure;

   Sammanfattning : The most important and widely used group of metallic alloys is steels, whichare alloys of the element iron together with carbon and usually other elementssuch as B, N, V, Nb and Cr. The strength in these alloys is closely connectedto the distribution of point defects, precipitates and grain boundaries whicheffectively act as obstacles for dislocation migration. LÄS MER

5. 4. Theoretical studies of boron and transition-metal carbonitride additions in steels

   Författare :Dan Fors; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Electronic structure; Dislocation network; Interfaces; Peierls-Nabarro model; Density functional theory; Steels; Coarsening; Diffusion; Misfit; Precipitates;

   Sammanfattning : Martensitic 9-12%Cr steel alloys are today widely used as critical components in fossil-fired steam power plants with steam temperatures up to 600°C, where sound oxidation resistance and excellent creep strength are required. Their strength and long-term creep resistance are closely connected to the presence and stability of Cr-rich M23C6 (M = Cr, Fe) carbides and densely distributed MX precipitates (M = transition metal, X = C or N), which effectively act as obstacles for dislocation migration.

7. 5. On cobalt-chrome frameworks in implant dentistry

   Författare :Lars Hjalmarsson; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cobalt-chrome; titanium; implants; misfit; corrosion; viability; abutment-free;

   Sammanfattning : Background: Cobalt-chrome (CoCr) alloys have been used in dentistry in decades but very little is known about their behavior and biological impact as framework materials in implant dentistry. Furthermore, few studies have evaluated and compared the clinical and radiological results of abutment and abutment-free implant treatment concepts. LÄS MER
