Environmentally Assisted Cracking & Hydrogen Embrittlement

• Proposers: Jesus Toribio, Hrihoriy Nykyforchyn

• Summary: Environmentally assisted cracking is a general phenomenon of material degradation and fracture present under any circumstance, since any environment is potentially aggressive from the point of view of the damage/failure process. It has received many names in the scientific literature such as stress corrosion cracking, environment sensitive cracking, localized anodic dissolution. etc.

With regard to hydrogen embrittlement, it is a particular case of environmentally assisted fracture present under many circumstances, specially when cathodic potentials appear or hydrogenating environments are present. It has also received many names (apart from the classical term "hydrogen embrittlement", may be not the most adequate but the most widely used worlwide). Other terms are hydrohen degradation, deterioration, damage, micro-damage, etc.

This minisymposium aims to cover any phenomenon of environmental degradation, including (i) those under static loading: corrosion, stress-corrosion, chemical attack, pitting, hydrogen embrittlement, hydrogen assisted cracking, hydrogen assisted fracture, hydrogen damage, hydrogen assisted micro-damage, hydrogen enhanced localized plasticity (HELP), hydrogen enhanced decohesion (HEDE), ...., and (ii) those under cyclic loading: corrosion-fatigue and hydrogen-assisted fatigue.
