An den warmfesten Kraftwerksstählen 30CrMoNiV4-11 und X10CrMoVNb9-1 wurde das Risseinleitungs- und Rissausbreitungsverhalten unter Kriechermüdungsbeanspruchung untersucht. Geprüft wurden Proben vom Typ CT und DENT in unterschiedlichen Abmessungen unter kraftkontrollierter Zugschwellbeanspruchung. Beanspruchungen mit Haltezeiten zwischen 0,1 h und 10 h decken den für die Versagensvorhersage besonders interessierenden Bereich der Interaktion zyklischer und statischer Schädigung ab. Die Durchführung langzeitiger Versuche mit Laufzeiten bis ca. 8000 h bzw. 30000 LW bietet unter Berücksichtigung der zeitabhängigen Entfestigungsvorgänge im Kriechbereich eine notwendige Grundlage für die Übertragbarkeit der experimentellen Ergebnisse auf das Bau-t...
