  1. 1. Modelling the system Cr-Fe-Ni-Te via the CALPHAD method, DFT and experiments : for fast nuclear reactor applications

    Författare :Carl-Magnus Arvhult; Malin Selleby; Jean-Marc Joubert; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Phase diagrams; Calphad; thermodynamics; microscopy; XRD; thermal analysis; phase transitions; nuclear materials; Teknisk materialvetenskap; Materials Science and Engineering;

    Sammanfattning : In the pursuit of safer, more environmentally friendly and sustainable forms of energy production for our ever growing demands, a type of nuclear reactor cooled by liquid metal instead of water is under development. Specific to this type of reactor are special forms of corrosion of the material that encapsulates the fuel pins in the reactor core, called Fuel-Clad Chemical Interaction (FCCI) or Fission Product-induced Liquid Metal Embrittlement (FPLME).

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

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

    Sammanfattning : 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. LÄS MER

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

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

    Sammanfattning : 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. LÄS MER

  5. 4. Transition Metals and their Carbides, Nitrides and Carbonitrides : from a CALPHAD Perspective

    Författare :Fredrik Haglöf; Malin Selleby; Andreas Blomqvist; Susanne Norgren; Mauro Palumbo; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknisk materialvetenskap; Materials Science and Engineering;

    Sammanfattning : The CALPHAD (CALculation of PHAse Diagrams) method consists of three cornerstones, i.e. experiments, computational methods (e.g. LÄS MER

  7. 5. Developing the third generation Calphad models and descriptions: a journey from unary to higher-order systems

    Författare :Zhangting He; Malin Selleby; Huahai Mao; Andreas Blomqvist; Gabriele Cacciamani; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknisk materialvetenskap; Materials Science and Engineering;

    Sammanfattning : The third generation Calphad descriptions aim to provide more accurate computational thermodynamics for an extended temperature range, i.e. from 0 K to high temperatures. In order to achieve such a goal, new Calphad models are needed. LÄS MER
