Abstract
Significant efforts have been invested into deformation/hydrogen interaction
affecting the mechanical response. By adopting a material approach, elasticplastic
polycrystalline and single crystal systems were selected accompanied by
comprehensive mechanical characterization. In the current study, a major activity
section is centered on metastable austenitic stainless steel interacting with
external/internal low fugacity hydrogen. Subsequent events due to free hydrogen
interaction have been tracked, enjoying the assistance of experimental advances to
match improved computational capabilities. In order to define better the crack-tip
mechanical environment, fracture mechanics methodology was supplemented,
namely, important step to reduce ambiguity, so typical to multi-parameter and
complex problems.
