Abstract
While there are a half-dozen or more hydrogen embrittlement models, only two of these, aside from hydrides, can survive: that of hydrogen enhanced localized plasticity (HELP) and that of hydrogen enhanced decohesion (HEDE). HEDE is often favored because of the synergism between hydrogen and metalloid segregants. In terms of crack thresholds and velocities, two critical experiments are reported. The first is associated with cracks in a highly dislocated network as opposed to a sparse network and how this affects threshold. The second deals with previously untested material wherein the kinetics be utilized to predict the hydrogen effect on threshold stress intensity in single crystal NiAl.
