项目摘要
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.
在温度和氢气压力等环境载荷作用下,通过声发射原始波形分析,了解金属氢分离膜在静破裂时的裂纹萌生和扩展特征。该方法可应用于bcc单相氢分离膜的结构健康监测,如各种Nb、v、ta基合金,验证了该方法作为综合耐久性评价体系的有效性。在此基础上,提出了混合结构的性能调整合金膜,并进行了上述耐久性评价试验,给出了实际应用时的推荐氢压力。
