Abstract

Though numerous studies have been devoted to hydrogen embrittlement in steels, up to date there is not a general agreement about the effect of hydrogen on the mechanical behaviour. The purpose of this paper is to analyze the influence of hydrogen on the mechanical response of high strength steels. Samples were cathodically charged with hydrogen, previous to low cyclic fatigue and tensile tests at room temperature. The presence of hydrogen produces softening effects on the cyclic behaviour and improvements in the fatigue life for low hydrogen contents. The stress-strain curves of tensile tests on pre-charged samples depend on the strain rate imposed. Both tensile and fatigue response could be explained by the hydrogen enhancement of dislocation mobility mechanism.

Kurzfassung

Obwohl sich eine Vielzahl an Studien mit der Wasserstoffversprödung in Stählen beschäftigt hat, gibt es bis heute keine Übereinstimmung über die Wirkung von Wasserstoff auf das mechanische Verhalten. Dieser Artikel beschäftigt sich mit der Analyse des Einflusses von Wasserstoff auf die mechanische Reaktion von hochfestem Stahl. Proben wurden vor zyklischen Ermüdungs- und Zugtests bei Raumtemperatur kathodisch mit Wasserstoff geladen. Das Vorhandensein von Wasserstoff führt oft zu Erweichungseffekten im zyklischen Verhalten und Verbesserungen der Ermüdungsbeständigkeit für geringe Wasserstoffgehalte. Die Spannungs-Dehnungs-Kurven der Zugtests für die vorgeladenen Proben hängen von der angelegten Dehnungsgeschwindigkeit ab. Sowohl die Zug- als auch die Ermüdungsreaktion können durch die hydrogene Verbesserung des Versetzungsbeweglichkeitsmechanismus erklärt werden.
