This research group has reported that the introduction of hydrogen into pure Ni at the same temperature conditions causes a relative decrease in Young's modulus of about 6-8%. Such a change is undesirable in magnetostrictive vibrating power generation, and a hydrogen recovery mechanism from hydrogen-soluble materials is required. In this study, we investigated the effectiveness of hydrogen recovery from Ni under the same temperature conditions by considering the possibility of hydrogen solid-phase diffusion by making a contact with Ti, which has a different enthalpy of hydrogen solid solution.
