Abstract

V diplomskem delu so obravnavana visokotrdnostna jekla za gradnjo hidroopreme. Pri varjenju teh jekel se najpogosteje pojavljajo kritične mikrostrukture z izrazito krhkostjo v toplotno vplivanem področju. Zaradi navedenega moramo posebno pozornost posvetiti metalografski analizi nastalih realnih mikrostruktur zvarnega spoja in določitvi faktorja trdnostne neenakosti. Natančna določitev področij krhkih mikrostruktur predstavlja pomemben dejavnik pri varnosti energetske konstrukcije.

Secondary title: Role and formation of brittle microstructure in the hsla steels for hydro equipment
Secondary abstract: In my diploma thesis the high-strenght steels for the construction of hydro equipment are discussed. When welding these steels, critical microstructures which are very fragile in the heat affected zone most frequently occur. Due to this fact, we have to pay special attention to metallographic analysis of the real microstructures weld joints and to the factor determining inequality. The precise identification of the areas of the fragile microstructures is an important factor in the safety of the energy structure.
