Abstract
The behavior of hydrogen in metals has attracted considerable interest in various areas, particularly materials degradation and energy conversion. The adverse effect of hydrogen on the mechanical properties of steels and other alloys has long been known and has prompted numerous studies of hydrogen in metals and alloys aimed at understanding the processes leading to hydrogen embrittlement.1–3 The use of hydrogen as a reactant in batteries and fuel cells has also promoted research on the storage of hydrogen either in the hydride or molecular form.4–7 In both the embrittlement and energy areas, the demand for improved performance of materials has created an emphasis on acquiring a knowledge of the absorption and transport characteristics of hydrogen in metals.KeywordsGalvanostatic ChargeHydrogen PermeationInput SurfaceReversible TrapHydrogen EntryThese keywords were added by machine and not by the authors.
