| Abstract Scope |
An outstanding question in hydrogen embrittlement is do dislocations play any role in the process. This talk will combine what we have learned directly and indirectly about the behavior of dislocations in the presence and absence of hydrogen by performing deformation experiments in a gaseous hydrogen environment in a controlled-environment transmission electron microscope and by characterizing the microstructure of hydrogen-charged and hydrogen-free metals subjected to uniaxial, torsional and fatigue loading. These experimental observations will be discussed in terms of the dominant fundamental mechanisms of hydrogen embrittlement. |
