Outline of Final Research Achievements |
We have elucidated that anomalous behavior of hydrogen embrittlement and corrosion induced by the hydrogen absorption during corrosion for high corrosion resistant alloys including stainless steel and Ni-Ti superelastic alloy by various tests such as hydrogen thermal desorption analysis and electrochemical measurements. The behavior of the alloys often differs from that of high strength steels. In particular, the dynamic interactions between hydrogen and the martensite transformation markedly affect the hydrogen embrittlement and corrosion behavior. The findings obtained in the present study are expected to the guide for the measurements of the life time and the improvements of reliability for high corrosion resistant alloys.
