The continuous increment of durability and reliability requirements for many machinery components is significantly enhancing the research activity in the Very‐High‐Cycle Fatigue (VHCF) characterization of metallic materials, in particular of high‐strength steels for critical structural applications. According to the area model, the VHCF strength of high‐strength steels can be estimated from the projected area of the ‘Optically Dark Area’ (ODA), which plays a key role in the VHCF response of high‐strength steels: more than 95% of the total VHCF life is consumed in the ODA formation, with crack growing even though the Stress Intensity Factor (SIF) is below the threshold for crack growth. Following the hydrogen embrittlement theory proposed by Murakami, hydrogen is supposed to assist crack growth within the ODA. The present paper proposes a general SIF formulation for the analytical model of the hydrogen assisted crack growth within the ODA. Starting from the general SIF formulation, a general expression for the material fatigue limit is obtained in the paper. The statistical method for the estimation of the parameters involved in the proposed model is finally illustrated in the paper and numerically applied to an experimental dataset.

“…Hydrogen-assisted fatigue crack-growth (HAFCG) in structural steels [1][2][3][4] is of significant concern, particularly with respect to the storage of compressed gaseous hydrogen in a futurehydrogen energy-based economy. In the presence of hydrogen, two types of cracking behavior are generally accepted in steels, i.e., stress-controlled fracture in high-strength steels and strain-controlled, quasi-static fracture in low-to medium-strength steels [5].…”

Multi-scale observation of hydrogen-induced, localized plastic deformation in fatigue-crack propagation in a pure iron

et al. 2017

View full text Add to dashboard Cite

In order to study the influence of hydrogen on plastic deformation behavior in the vicinity of the fatigue crack-tip in a pure iron, a multi-scale observation technique was employed, comprising electron channeling contrast imaging (ECCI), electron back-scattered diffraction (EBSD) and transmission electron microscopy (TEM). The analyses successfully demonstrated that hydrogen greatly suppresses the dislocation structure evolution around the fracture path and localizes the plastic flow in the crack-tip 2 region. Such clear evidence can reinforce the existing model in which this type of localized plasticity contributes to crack-growth acceleration in metals in hydrogen atmosphere, which has not yet been experimentally elucidated.
