Badaniom metaloznawczym poddano stal HR3C w stanie dostawy oraz po procesie starzenia w temperaturze 600°C i 700°C w czasie do 10 000 godzin. Zakres przeprowadzonych badań obejmował: badania strukturalne za pomocą skaningowej mikroskopii elektronowej oraz badania mechaniczne: pomiar twardości i próbę udarności. Stal HR3C w stanie dostawy dostarczana jest po przesycaniu. Charakteryzuje się mikrostrukturą...
Purpose: The purpose of the investigations was to determine changes in the microstructure and mechanical properties of HR3C creep resisting austenitic steel after service. Design/methodology/approach: The investigations were performed on test specimens taken from a part of the steam superheater tube. The range of the investigations included: microstructural investigations - light and SEM microscope;...
