  2. 11. Computational Materials Design of Medium Mn Steels

    Author : Fei Huyan; Annika Borgenstam; Peter Hedström; Marcel Somers; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Medium Mn steels (~ 3–10 mass % Mn), a new category of advanced high strength steels, attracted worldwide research interests recent years due to their excellent mechanical properties and low cost. These steels have fine microstructures and contain large fraction of metastable retained austenite (~ 30 volume %), therefore exhibit excellent strength and elongation. READ MORE

  4. 12. First-Principles Investigation of Bulk and Interfacial Properties of Cu-Co Binary System

    Author : Changle Li; Levente Vitos; Hongbin Zhang; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Teknisk materialvetenskap; Materials Science and Engineering;

    Abstract : Due to the complex nature of phase interfaces, acquiring precise interfacial energies is usually a big challenge for both experimental measurements and computational modelings. In this thesis, we put forward an efficient route for assessing the temperature dependence of the interfacial energy using density functional theory (DFT). READ MORE

  5. 13. Development Towards Sustainable Ironmaking : The IronArc Process

    Author : Jonas Svantesson; Mikael Ersson; Robert Eriksson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; IronArc; Refractory wear; plasma generator; freeze-lining; Teknisk materialvetenskap; Materials Science and Engineering;

    Abstract : The IronArc process is a novel process for a more sustainable production of liquid pig iron using electricity for heating and hydrocarbons for reduction. This thesis aims to facilitate its use by investigating possible refractory solutions and the gas blowing in the process which is done by a plasma generator. READ MORE

  6. 14. Simulation of diffusional processes in alloys : techniques and applications

    Author : Henrik Strandlund; John Ågren; John Morral; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Diffusion; Kirkendall effect; Phase transformations; Random walk; Solute drag; Interfacial mobility; Other materials science; Övrig teknisk materialvetenskap;

    Abstract : This thesis concerns computer simulation of diffusional processes in alloys. The main focus is on the development of simulation techniques for diffusion in single-phase domains, but also diffusion controlled phase-transformations and interfacial processes are discussed. READ MORE

  7. 15. Simulation of Phase Transformations and coarsening : Computational tools for alloy development

    Author : Johan Jeppsson; John Ågren; Gerhard Inden; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Teknisk materialvetenskap;

    Abstract : The final properties of an alloy are highly interlaced with its microstructure. It is therefore essential to control the evolution of the microstructure of the material during the fabrication process. Nowadays, materials design involves an increasing part of computational design to complement the traditional experimental trial and error approach. READ MORE
