Web9 apr. 2024 · The influence of strain rate in the interval of (10−5–10−3) 1/s on room temperature tensile behavior, dislocation arrangement, deformation mechanisms, and fracture of austenitic stainless steel AISI 316L electrochemically charged with hydrogen was investigated. Independently on strain rate, hydrogen charging provides the … During the cathodic hydrogen charging, hydrogen can be formed at the cathodically polarized electrode due to the applied potential. Further, depending on the medium, an additional material degradation and the associated formation of hydrogen can occur. It should be noted that the sample is … Meer weergeven During the immersion test, the amount of hydrogen absorbed depends primarily on the corrosion attack on the sample and subsequently on the presence of hydrogen poisons. The results of the aging tests can be seen in … Meer weergeven The influence of the current density is shown in Fig. 9.
