  2. 1. On high temperature oxidation resistance : Towards the materials genome of high temperature alloys

    Author : Samuel Hallström; John Ågren; Roger Reed; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials Science and Engineering; Teknisk materialvetenskap;

    Abstract : The efficiency of a heat engine increases with increasing service temperature. This leads to a demand for material that can withstand aggressive environments and sometimes also high load at higher and higher temperature. That is the rationale for the work of this thesis. READ MORE

  4. 2. First step to a genomic CALPHAD database for cemented carbides : C-Co-Cr alloys

    Author : Zhou Li; Malin Selleby; Jana Pavlu; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CALPHAD; Einstein model; two-state model; compound energy formalism; thermodynamic description; C-Co-Cr; Teknisk materialvetenskap; Materials Science and Engineering;

    Abstract : CALPHAD (CALculation of PHAse Diagrams) denotes the methodology used to assess thermodynamic data based on experiments as well as on first principles calculations. Essential for this method is the coupling of phase diagram and thermodynamic properties. READ MORE

  5. 3. Low Temperature Austenite Decomposition in Carbon Steels

    Author : Albin Stormvinter; Annika Borgenstam; John Ågren; Peter Hedström; John G. Speer; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Carbon steels; Electron backscattered diffraction; Martensite; Microscopy; Microstructure; Thermodynamic modeling;

    Abstract : Martensitic steels have become very important engineering materials in modern society. Crucial parts of everyday products are made of martensitic steels, from surgical needles and razor blades to car components and large-scale excavators. READ MORE

  6. 4. Thermodynamic and Kinetic Investigation of the Fe-Cr-Ni System Driven by Engineering Applications

    Author : Wei Xiong; Malin Selleby; John Ågren; Byeong-Joo Lee; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; phase transformation; magnetism; spinodal decomposition; stainless steel; low temperature CALPHAD; phase field; ab initio; atom probe tomography; calorimetry; SRA - E-vetenskap SeRC ; SRA - E-Science SeRC ; SRA - Energy; SRA - Energi;

    Abstract : This work is a thermodynamic and kinetic study of the Fe-Cr-Ni system as the core of stainless steels. The Fe-Cr, Fe-Ni and Cr-Ni systems were studied intensively using both computational and experimental techniques, including CALPHAD (CALculation of PHAse Diagrams), phase field simulation, ab initio modeling, calorimetry, and atom probe tomography.

  7. 5. Thermodynamic Database for Zirconium Alloys

    Author : Rosa Jerlerud Pérez; Bo Sundman; Arthur Motta; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Zirconium alloys; thermodynamic equilibrium; thermodynamic properties; binary system; ternary system; Gibbs energy; Thermo-Calc; Calphad; binary system; ternary system; Other materials science; Övrig teknisk materialvetenskap;

    Abstract : For many decades zirconium alloys have been commonly used in the nuclear power industry as fuel cladding material. Besides their good corrosion resistance and acceptable mechanical properties the main reason for using these alloys is the low neutron absorption. READ MORE
