  1. 1. Thermodynamic modelling and assessment of some alumino-silicate systems

    Author : Huahai Mao; Bo Sundman; Gunnar Eriksson; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; thermodynamic modelling; thermodynamic assessment; alumino-silicate system; slag; oxide system; CALPHAD; phase diagram; phase equilibrium; Thermo-Calc; compound energy formalism; ionic two sub-lattice liquid model; AlO2-1 species; Al2O3; CaO; MgO; SiO2; Y2O3; Materialvetenskap; Materials science; Teknisk materialvetenskap;

    Abstract : Alumino-silicate systems are of great interest for materials scientists and geochemists. Thermodynamic knowledge of these systems is useful in steel and ceramic industries, and for understanding geochemical processes. A popular and efficient approach used to obtain a self-consistent thermodynamic dataset is called CALPHAD. READ MORE

  2. 2. Developing the third generation of Calphad databases: what can ab-initio contribute?

    Author : Sedigheh Bigdeli; Malin Selleby; Huahai Mao; Nathalie Dupin; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Developing the third generation of Calphad databases with more physical basis valid within a wider temperature range is the aim of the present work. Atomistic scale (ab-initio) methods, particularly techniques based on DFT theory, are used for modelling dierent phenomena, so as to gauge the capacity for use in Calphad modelling. READ MORE

  3. 3. Profitability = f(G) : Computational Thermodynamics, Materials Design and Process Optimization

    Author : David Dilner; Malin Selleby; Mao Huahai; André Costa e Silva; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CALPHAD; steel; sulfide; steelmaking; thermodynamics; ICME; CALPHAD; stål; sulfid; ståltillverkning; termodynamik; ICME; Materials Science and Engineering; Teknisk materialvetenskap;

    Abstract : The thesis starts by giving a motivation to materials modeling as a way to increase profitability but also a possibility decrease the environmental impact. Fundamental concepts of relevance for this work are introduced, this include the materials genome, ICME and of course the CALPHAD method. READ MORE
