  2. 1. First-principles investigations of ordering in binary alloys

    Author : Moshiour Rahaman; Andrei Ruban; Staunton Julie; KTH; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; ordering; random; alloys;

    Abstract : The aim of the thesis is to study ordering in binary alloys on the basis of first-principles or {\it ab-initio} techniques employing density functional theory (DFT). The ordering phenomena of materials are of crucial importance for technological applications. READ MORE

  4. 2. Thermodynamic Database for Zirconium Alloys

    Author : Rosa Jerlerud Pérez; Bo Sundman; Arthur Motta; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; 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

  5. 3. Modulating magnetic interactions : in metamaterials and amorphous alloys

    Author : Nanny Strandqvist; Björgvin Hjörvarsson; Alexei Vorobiev; Sean Langridge; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Magnetic metamaterials; interlayer exchange coupling; superlattice; mesospins; magnetic nanostructures; emergence; amorphous alloys; CoAlZr; FeZr; Fysik; Physics;

    Abstract : This thesis is focused on exploring and modulating magnetic interactions in metamaterials and amorphous alloys along one-, two-, and three-dimensions. First, thin films of alternating Fe and MgO are adapted to modulate magnetic interactions along one dimension. READ MORE

  6. 4. Characteristics of cast magnesium alloys : microstructures, defects and mechanical properties

    Author : Haiping Cao; Anders Jarfors; Linköpings universitet; []
