Effect of internal hydrogen on the fatigue crack growth of HT-9

  • 1. Pacific Northwest Lab., Richland, WA

Description

A previous evaluation indicated that under certain circumstances hydrogen could cause subcritical crack growth of HT-9 in a fusion reactor environment. This previous evaluation only examined static load conditions and it was noted that there is a lack of data on hydrogen effects on fatigue crack growth of HT-9; however, the fatigue crack growth properties of steels are sensitive to hydrogen. Therefore, the objective of this study was to determine the effects of hydrogen on the fatigue crack growth of HT-9 and to develop a data base which could be used for modeling these effects. 14 refs., 16 figs., 5 tabs
