Characterization of Reactor Pressure Vessel Steel by ABI Testing

Publication date: 2016 Source:Procedia Materials Science, Volume 12 Author(s): Petr Haušild, Jan Siegl, Aleš Materna, Miloš Kytka, Radim Kopřiva Microstructure of the base metal, the multilayer welding seam and the two-layer cladding was characterized through the thickness of the WWER 440 reactor pressure vessel wall. Mechanical properties were determined by performing a series of instrumented indentations across the weld at room temperature. The results were treated by so-called automated ball indentation technique. Mechanical properties obtained by instrumented indentation from the local stress-strain behavior were compared with minimum values required by the standard.
