Abstract

A model, which relates the deviation of diffusion coefficient of hydrogen in amorphous alloys from the Arrhenius law to the temperature dependence of the short-range order (SRO), was developed. The SRO in the amorphous structure was defined on the basis of radial distribution function (RDF) of amorphous iron and its temperature dependence. The activation energy for hydrogen diffusion was found to increase significantly as a result of alloying with either silicon or boron. It was observed that at low concentrations of the alloying element, silicon and boron has similar influence on the activation energy, although boron increased slightly more.
