Abstract
The various objections to the Petch-Stables theory of hydrogen embrittlement are reviewed. Most of these objections are shown to be inappropriate or subject to removal. It is concluded that the Petch-Stables theory is fundamentally sound, but incapable of explaining the large decreases in fracture toughness observed in high strength structural steels subjected to hydrogen containing environments.Keywords
