Changes in certain structure-sensitive properties (microhardness, cyclic ductility, X-ray diffraction linewidth) of steel fatigued in the low endurance range in air and in a hydrogen-charging medium were investigated. The results of a study of crack nucleation and propagation are described, and a mechanism of intergranular fatigue fracture in the low endurance range is postulated.
