Synergism effects of hydrogen and radiation defects in steel

There is a hypothesis which postulates the microstructural radiation defects as effective traps for hydrogen and this deposited hydrogen as a stabilizer of these features. Thus, the higher the content of hydrogen the stronger is the embrittlement. The H-trap hypothesis should be examined by a SANS experiment.

The measurement has shown that we can detect H-deposition (> 1x10-4 wt.-%) by SANS.
