  2. 1. Microstructure of Zirconium Alloys Oxidized in Steam

    Author : Pia Tejland; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; EDX; ADF; TEM; Zircaloy-2; FIB-SEM; STEM; GD-OES; SPP; SEM; Zirconium; HAADF;

    Abstract : Zirconium alloys are widely used in nuclear reactors as fuel cladding tubes because of their low thermal neutron capture cross-section, good corrosion properties and satisfactory mechanical properties. However, the main limiting factor of these materials is the oxidation behavior. READ MORE

  4. 2. 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

  6. 4. Zirconium dioxide based dental restorations : studies on clinical survival and fracture behaviour

    Author : Christel Larsson; Malmö högskola; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Zirconium dioxide; Y-TZP; Dental restorations;

    Abstract : POPULÄRVETENSKAPLIG SAMMAN-FATTNINGAtt förlora tänder påverkar en människas utseende och funktioner såsom tal och tuggning. Det finns därmed ett behov att rehabilitera och ersätta förlorade tänder för att upprätthålla en god livskvalitet. READ MORE

  7. 5. Mechanistic Approach to Corrosion of Zirconium by Water - A First Principle Study

    Author : Mikaela Lindgren; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; zirconium; hydrogen pick-up; corrosion; oxygen vacancy; DFT;

    Abstract : Zirconium and zirconium oxides are of major technological importance. There are broad applications for these materials, from fuel cell electrolyte to semiconductors and in hip-implants. In nuclear power plants, zirconium alloys are widely used as cladding material to contain the fission fuel in the reactor cores. READ MORE
