Development of β-Ray Tracking Technique for Studying Hydrogen Behavior of Radiation Damaged Fe-Cr-Ni Alloy

Abstract

Hydrogen behavior in an Fe-Cr-Ni alloy is very important for the investigation of hydrogen embrittlement. This paper shows the hydrogen trapping sites in an Fe-Cr-Ni alloy, which have not been clarified with conventional techniques, using β-ray tracking technique. This technique, application of tritium TEM-ARG (transmission electron microscopic autoradiography) technique, is applied to the visualization of hydrogen trapping sites in a radiation damaged Fe-Cr-Ni alloy.
