  1. 6. Theoretical modeling of molar volume and thermal expansion

    Författare :Xiao-Gang Lu; Bo Sunsman; Michel Jacobs; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; first-principles calculations; ab initio; Calphad; Debye-Grüneisen model; thermodynamic properties; elastic modulus; volume; thermal expansivity; pressure; Thermo-Calc; VASP; element; carbide; nitride; Materialvetenskap; Materials science; Teknisk materialvetenskap;

    Sammanfattning : Combination of the Calphad method and theoretical calculations provides new possibilities for the study of materials science. This work is a part of the efforts within the CCT project (Centre of Computational Thermodynamics) to combine these methods to facilitate modeling and to extend the thermodynamic databases with critically assessed volume data.

  3. 7. Applications of Computational Thermodynamics and Kinetics on Transformations in Stainless Steels

    Författare :Sten Wessman; Malin Selleby; Staffan Hertzman; Bosse Sundman; Hannu Hänninen; KTH; []
    Nyckelord :Stainless Steels; Duplex; Ferrite; Austenite; Computational Thermodynamics; Thermo-Calc; Dictra;

    Sammanfattning : Stainless steels are high-alloyed, usually with multiple components and often also dual matrix phases, as for duplex stainless steels. This make predictions and calculations of alloying effects on equilibria and transformations complicated. LÄS MER

    Sammanfattning : This thesis focuses on the AOD process, which is an important metallurgical reactor in stainless steel production. To be more specific, the thesis is limited to study the decarburisation step, which is the first of three process steps in the AOD converter. LÄS MER

  7. 10. Computational tools for simulation of phase transformations

    Författare :Mikael Schalin; KTH; []
    Nyckelord :;

    Sammanfattning : A new software package, Thermite, for thermodynamiccalculations and process simulation is developed around theThermo-Calc databank. Thermite is a computational toolbox forequilibrium calculations and simulation of phasetransformations. It provides graphic visualisation and allowsmanipulation of the presented data. LÄS MER
