Popis:	This paper deals with the effect of hydrogen embrittlement on the fatigue life of steels. This phenomenon is typical for the gigacycle fatigue region, but we also encounter it in surface-treated materials. in which a subsurface crack initiation has occurred. In samples in which the fracture is affected by the presence of hydrogen embrittlement, subsurface fatigue crack initiation occurs. In this work we observe the change in toughness and local elastic modulus depending on the hydrogen diffusion of hydrogen over time.
