Towards a unified mechanism of the various forms of hydrogen occurrence in the aqueous corrosion of steel
After two previous reconsideration steps on cathodic charging and hydrogen stress cracking, then permeation measurements, a third step is presented on the SOHIC mechanism, and more generally any interaction between internal hydrogen and moving dislocations. This results in a unified mechanism for all forms of hydrogen damage, built ex-nihilo from the mere data on metal electronic structure, the physical state of the H+ ion in water, steel micrographic structure and dislocations movement. There are already many practical and theoretical consequences.
