  1. 1. First-principles investigations of planar defects

    Författare :Song Lu; Levente Vitos; Graeme Ackland; KTH; []
    Nyckelord :;

    Sammanfattning : Two types of planar defects, phase interface and stacking fault, are addressed in thisthesis. The first-principles exact-muffin orbitals method in combination with thecoherent-potential approximation is the main density functional theory (DFT) toolfor our studies. LÄS MER

  3. 2. Modelling of Formation and Evolution of Defects and Precipitates in Fe-Cr Alloys of Reactor Relevance

    Författare :Pär Olsson; Jan Källne; Jan Wallenius; Graeme Ackland; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nuclear physics; Kärnfysik; Nuclear physics; Kärnfysik;

    Sammanfattning : Fe-Cr alloys form the basis of many industrially important steels. Due to their excellent resistance to radiation induced swelling, ferritic steels are expected to be used for critical structural components in advanced nuclear systems, such as fast breeder reactors, accelerator driven systems and fusion reactors.
