| Research Abstract |
Environmental loads, such as temperature and a hydrogen pressure, were given to the metallic hydrogen separation membrane, and the characteristics of the crack initiation and propagation at the time of the static membrane fracture were understood in the present investigation by AE original waveform analyses. This approach could be applied to the structural health monitoring of bcc single phase hydrogen separation membranes, such as various Nb-, V-and Ta-based alloys, and the effectiveness as an integrated durability evaluation system was confirmed. Furthermore, the performance tuned alloy membranes of hybrid structure were proposed, and above durability evaluation tests were performed, and the recommendation applied hydrogen pressures were shown for practical applications.
