  1. 16. Thermodynamic Studies of the Fe-Pt System and “FeO”-Containing Slags for Application Towards Ladle Refining

    Författare :Patrik Fredriksson; KTH; []
    Nyckelord :Thermodynamics; Activity; Galvanic cell; Calorimetry; Gas equilibration technique; Iron-platinum alloys; FeO; Slags; Modelling; Ladle;

    Sammanfattning : In the present work, the thermodynamic activites of ironoxide, denoted as "FeO" in the slag systems Al2O3-"FeO", CaO-"FeO", "FeO"-SiO2, Al2O3-"FeO"-SiO2, CaO-"FeO"-SiO2and "FeO"-MgO-SiO2were investigated by employing the gasequilibration technique at steelmaking temperatures. Thestrategy was to expose the molten slag mixtures kept inplatinum crucibles for an oxygen potential, determined by aCO/CO2-ratio. LÄS MER

  3. 17. Groundwater characterisation and modelling

    Författare :Marcus Laaksoharju; KTH; []
    Nyckelord :;

    Sammanfattning : For the last 10 years, the Äspö Hard RockLaboratory (HRL) in Sweden has been the main test site for thedevelopment of suitable methods for the final disposal of spentnuclear fuel. Major achievements have been made in thedevelopment of new groundwater sampling and modellingtechniques. LÄS MER

  4. 18. Non-Local Thermodynamic Equilibrium Spectral Modelling of Kilonovae

    Författare :Quentin Pognan; Anders Jerkstrand; Kyohei Kawaguchi; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Transients: Neutron Star Mergers; Radiative Transfer; Astronomy; astronomi;

    Sammanfattning : The astrophysical origin of rapid neutron capture (r-process) elements has long remained a puzzle and been the object of scientific debate. Neutron star (NS) mergers have historically been suggested as an ideal site for the creation of these elements, and were propelled into focus following the detection of the first binary neutron star (BNS) merger in 2017.

  7. 20. Creep modelling of particle strengthened steels

    Författare :Hans Magnusson; Rolf Sandström; Wolfgang Blum; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; creep rate modelling; particle hardening; microstructure evolution; dislocation climb; ferritic steels; Materials science; Teknisk materialvetenskap;

    Sammanfattning : Materials used in thermal power plants have to resist creep deformation for time periods up to 30 years. Material evaluation is typically based on creep testing with a maximum duration of a few years. This information is used as input when empirically deriving models for creep. LÄS MER
