Hydrogen embrittlement of irradiated alloys

TL;DRAbstract

stress, the predicted relationship between incubation time and stress agreed reasonably well with experimental data. Hydrogen Embrittlement and Strain Aging In Titanium Alloys. Low Strain rate embrittlement in titanium alloys can be classified as a strain aging phenomenon. Prestraining and aging an alpha-beta titanium alloy resulted in a ductility minimum at some intermediate aging time. It appears that hydrogen migrates to a region of inhomogeneous strain, where a high stress state exists, and creates this embrittlement. The restoration of ductility at long aging times was attributed to recovery with subsequent redistribution of hydrogen. Low strain rate hydrogen embrittlement was obtained for an alpha alloy and a beta alloy. Hydrogen in small quantities seemed to aid creep resistance in the alpha alloy. The beta alloy was resistant to nominal quantities of hydrogen (420 ppm), but did show embrittlement at higher levels. Hydrogen Embrittlement of Several Face- Centered Cubic Alloys. T
