Caskey, G. R.

The onset of plastic instability, localization of plastic flow, and fracture in Type 304L austenitic stainless steel are modified by the presence of hydrogen. It is not certain, however, whether the observed changes in behavior are attributable to the direct effect of hydrogen on plastic flow or to the intervention of a hydrogen-induced brittle fracture process. The effects are observed in both smooth bar and single edge notched specimens and are dependent on deformation temperature.
