Home > Diffusion of Hydrogen Isotopes in Metals
The diffusion and trapping of hydrogen in pure metals and in alloys is an important topic in research on nuclear fusion reactor materials and hydrogen storage technologies. It is well-known that, because of its small size, hydrogen diffuses readily in many metallic systems, where its complex behaviour can be the cause of damaging effects (embrittlement, corrosion, cracking) which may compromise their structural integrity.
This database collects experimentally and theoretically-derived data relating to the parameterisation of models for the temperature-dependent diffusivity of hydrogen isotopes in relevant materials.
