摘要:
The introduction of solute hydrogen in high purity aluminum has been studied using a variety of experimental techniques. Very large hydrogen concentrations were introduced by electrochemical charging and by chemical charging. Length change and lattice parameter measurements showed that the hydrogen was trapped at vacancies which entered in a ratio close to C-v/C-H=1. Small angle X-ray scattering showed that the hydrogen-vacancy complexes clustered into platelets lying on the {111}.
