Hydrogen in Metals

Abstract

A brief summary is presented of the known effects of hydrogen on metals, especially degradation and embrittlement.Practical problems involving hydrogen are surveyed.Resume-On presente un brefresume des effets connus de l'hydrogene sur les metaux, surtout en ce qui a trait it la degradation et la fragilisation de ceux-ci. On discute aussi de certains problemes pratiques relies it ces effets.

Experimental investigation on the performance of AISI 440C martensitic stainless steel against the formation of white etching areas under sliding dynamic loading

“…Some phases present in the metals act as a trapping site of hydrogen. Hydrogen becomes relatively immobile if two single atoms combine to form diatomic molecular hydrogen [12]. Immobile hydrogen does not contribute to the acceleration of formation of WEAs and WECs.…”
