  1. 11. Microstructure of Zirconium Alloys Oxidized in Steam

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

    Sammanfattning : 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. LÄS MER

  3. 12. Effect of metal and cubic carbide additions on interface chemistry, phase composition and grain growth in WC-Co based cemented carbides

    Författare :Jonathan Weidow; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; APT; TEM; EBSD; SEM; EDX;

    Sammanfattning : A cemented carbide is a composite material used in metal cutting operations. A hardness providing WC-based skeleton is embedded in a toughness providing binder, mainly consisting of Co. The material is produced by powder metallurgical methods. LÄS MER

  5. 14. Development of Cermet Microstructures during Sintering and Heat-Treatment

    Författare :Jenni Zachrisson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; APFIM; EELS; cemented carbides; quantitative microanalysis; gradients; N ; TEM; EFTEM; hardmetals; EDX; Ti C; light elements;

    Sammanfattning : The work presented in this thesis is concerned with the microstructure of Ti(C, N) based cermet materials used in cutting tool applications. Several techniques have been used to study the microstructure of cermets, in particular transmission electron micro-scopy in combi-na-tion with energy dispersive X-ray analysis and electron energy-loss spectroscopy, energy-filtered transmission electron micro-scopy, atom-probe field-ion microscopy and scanning electron microscopy.
