Abstract
In this paper the effect of different levels of plastic deformation on hydrogen permeation of cold rolled or tensile specimen of API 5L X65 pipeline steel is given using the three techniques: Subsequent Transients (method of ISO 17081), partial transients and desorption technique. In the case of fatigue testing the smooth flat X65 specimens are continuously charged at the same time when the fatigue load was applied to study the effect of low frequency fatigue load on hydrogen permeation characteristic curve and diffusion coefficient of hydrogenFile in questo prodotto:
