  1. 16. Numerical simulation of weldment creep response

    Författare :Peter Segle; KTH; []
    Nyckelord :ABAQUS; constraint effect; continuum damage mechanics; creep; creep crack growth; design; design code;

    Sammanfattning : In-service inspections of high temperature pressureequipment show that weldments are prone to creep and fatiguedamage. It is not uncommon that severely damaged weldments arefound even before the design life of the component has beenreached. LÄS MER

  3. 17. Life assessment from weld microstructures at high temperatures

    Författare :Jan Storesund; KTH; []
    Nyckelord :;

    Sammanfattning : Most pressure vessels in fossil power plant are designed forcreep. After operation of the order of the design lifetime thematerial may be degraded and further operation is limited.Methods which can prolong the lifetime and assess thecomponents is therefore demanded. LÄS MER

  7. 20. Processing of Nanostructured WC-Co Powders and Sintered Steels

    Författare :Zongyin Zhang; KTH; []
    Nyckelord :Nanostructured powder; Chemical synthesis; Fe-Mn-Si steel; Fe-Cu swelling; Mechanical properties; Sintering parameters;

    Sammanfattning : Processing of nanostructured WC-Co and W-Co powders,modelling of Fe-Mn-Si alloy, swelling of Fe-Cu alloy, andmechanical properties and sintering of Fe-Mn-Si steels havebeen studied in the present thesis.W-Co precursors made by chemical synthesis were used toproduce nanostructured WCCo and W-Co powders by calcination,reduction and carburization.
