Abstract
AbstractHydrogen-charged nickel is known to exhibit serrated yielding over a range of temperatures when tested in tension below room temperature. This phenomenon is examined in detail by measuring the activation energy in strain rate change experiments performed at different temperatures and by using analyses similar to those available for dilute Fe-C alloys. The activation energy estimated is found to be strongly temperature-dependent. This is interpreted by considering the interaction of hydrogen with edge dislocations in terms of a proton and an electron, with the electrons entering the unfilled electron shells of nickel. A method for calculating variable binding energy for such a configuration is also given.
