Abstract:

In this report it is shown that the observed reduction in fatigue life as well as the exhaustion of ductility of uniform steel specimens due to the presence of interstitial hydrogen can be modelled theoretically as a result of the Intrinsic Time to Failure hypothesis recently introduced by Valanis. Laws of interaction between hydrogen diffusion and mechanical deformation of steel that predict quantitatively and for the first time the observed deflection of a steel beam in the presence of interstitial hydrogen have been found.
