A number of effects of hydrogen both as gas and dissolved in metal on the fatigue crack growth in steels, especially at the near threshold load, has been analysed: 1) the effect of gas adsorption on the effective fatigue threshold [delta]Kth eff; 2) analysis of hydrogen effect on the fatigue crack growth in structural steels in dependence of its strength and test temperature; 3) application of fracture mechanics approaches to the evaluation of high temperature hydrogen degradation of steels; 4) use of the [delta]Kth eff parameter for evaluation of the high temperature degradation of steels during operation in hydrogen-containing environment; 5) existence of three factors of ambiguous hydrogen influence on [delta]Kth eff; 7) fractografical peculiarities of the near threshold crack growth in the degraded steel; 9) a geometric model of crack closure in the hydrogenated steel caused by fracture surface roughness and the longitudinal shear; 10) scale effect of the fatigue threshold; variance of [delta]Kth under the plane strain conditions; dependence of [delta]Kth on the specimen thickness for the hydrogenated and degraded metal.
