  • The influence of microstructure on fracture toughness of undermatched weld metal = Vplyv mikroštruktúry na lomovú húževnatosṫ zvarového kovu s nižšou pomernou medzou sklzu
    Praunseis, Zdravko
    A set of BxB specimens was taken from homogeneous and heterogeneous welds and tested to obtain fracture behaviour of undermatched welded joints. The critical crack-tip opening displacement (CTOD), as ... the revelant parameter for safe service of welded structure, was used to evaluate the influence of microstructures. Surface cracks of different depths, was used to evaluate the influence of microstructures. Surface cracks of different depths were positioned in weld metal with fatigue-crack-tip front in different microstructures. It was shown that selection of soft weld consumable (wire) does not guarantee tough root layer in the undermatched.
