Hydrogen interacts with many metals to reduce their ductility (2) and frequently their strength also. It enters metals in the atomic form, diffusing very rapidly even at normal temperatures. During melting and fabrication, as well as during use, there are various ways in which metals come in contact with hydrogen and absorb it. The absorbed hydrogen may react irreversibly with oxides or carbides in some metals to produce a permanently degraded structure. It may also recombine at internal… Expand
The resistance to embrittlement by a hydrogen environment of selected high strength iron-manganese base alloys
Fe-16Mn and Fe-25Mn base alloys, which had been cold worked to yield strength levels of 201 and 178 KSI, were resistant to degradation of mechanical properties in a one atmosphere hydrogenExpand
Electrochemical Aspects of Hydrogen in Metals
The deleterious effect that hydrogen produces in metals, known popularly as hydrogen embrittlement, has been the root cause of innumerable investigations.(1–6) The hydrogen that producesExpand
The control of catalytic poisoning and stress corrosion cracking
When a structural metal is stressed in a hydrogen environment, the metal may crack at stress levels much lower than its normal strength. This embrittlement is caused by hydrogen atoms or ions ratherExpand
Hydrogen enhances strength and ductility of an equiatomic high-entropy alloy
Hydrogen in an equiatomic CoCrFeMnNi high-entropy alloy leads not to catastrophic weakening, but instead increases both, its strength and ductility, which opens new pathways for the design of strong, ductile, and hydrogen tolerant materials. Expand
Hydrogen degradation of steels and its related parameters, a review
Many steel structures can absorb varying amounts of hydrogen during manufacturing, processing such as electroplating or acid pickling and during service life by corrosion reactions or cathodicExpand
A strong and ductile medium-entropy alloy resists hydrogen embrittlement and corrosion
The authors show that a CoNiV medium-entropy alloy with face-centered cubic structure fulfils all the above criteria. Expand
The protective coatings of Al2O3 and AlN on iodide titanium in initial state and after annealing in a hydrogen atmosphere were investigated by scanning electron microscopy. It was found that theExpand
Hydrogen embrittlement through the formation of low-energy dislocation nanostructures in nanoprecipitation-strengthened steels
It is shown that the actual crack initiation is the dislocation nanostructure and its associated strain partitioning, and the appearance of the failure zone resembles the "fish eye" associated to inclusions as stress concentrators. Expand
Hydrogen – microstructure – mechanical properties interactions in super duplex stainless steel components
Abstract The increasing demand for energy requires the exploration of oil and gas fields at deeper water locations and on more severe conditions. These production systems have demanded the use ofExpand
Hydrogen–vacancy–dislocation interactions in α-Fe
Atomistic simulations of the interactions between dislocations, hydrogen atoms, and vacancies are studied to assess the viability of a recently proposed mechanism for the formation of nanoscale voidsExpand
