Effect of machining-induced surface residual stress on initiation of stress corrosion cracking in 316 austenitic stainless steel
TL;DR: In this paper, the effect of machining-induced surface residual stress on the stress corrosion cracking (SCC) initiation in 316 stainless steel was investigated in boiling magnesium chloride solution.
Journal ArticleDOI
Resolving the hydrogen effect on dislocation nucleation and mobility by electrochemical nanoindentation
TL;DR: In this article, the in situ effect of electrochemically charged hydrogen on the mechanical properties of austenitic stainless steel (ASS) was studied and a novel analysis method based on the Taylor assumption and the indentation size effect was used to calculate the effect of hydrogen on lattice friction.

Hydrogen embrittlement of catholically hydrogen-precharged 304L austenitic stainless steel: Effect of plastic pre-strain
TL;DR: In this paper, a group of flat specimens with different degrees of pre-strain (0 i.e., without prestrain, 3, 6, 10, 15, 20 and 25% true strain) was catholically hydrogen charged and then was strained immediately to fracture by means of tensile testing.

Experimental to study the effect of multiple weld-repairs on microstructure, hardness and residual stress for a stainless steel clad plate
TL;DR: In this paper, an experimental study of multiple repair welds in a stainless steel clad plate was conducted to determine the changes in microstructure, residual stress and micro hardness, and the results showed that the repair weld contains nine zones with different microstructures.

Hydrogen-enhanced localized plasticity—a mechanism for hydrogen-related fracture
TL;DR: In this article, a theory of hydrogen shielding of the interaction of dislocations with elastic stress centres is outlined, which can account for the observed hydrogen-enhanced dislocation mobility.
Journal ArticleDOI
Hydrogen embrittlement of metals
TL;DR: The deleterious effects of hydrogen on the tensile properties of metals are caused by the association and movement of hydrogen with dislocations as discussed by the authors, and hydrogen-dislocation interactions modify plastic deformation processes by stabilizing microcracks, by changing the work hardening rate, and by solid solution hardening.
Journal ArticleDOI
Permeability, solubility and diffusivity of hydrogen isotopes in stainless steels at high gas pressures
TL;DR: In this paper, the authors provide a framework for describing the permeability, solubility and diffusivity of hydrogen and its isotopes in austenitic stainless steels at temperatures and high gas pressures of interest for hydrogen storage and distribution infrastructure.
Journal ArticleDOI
Effect of strain-induced martensite on hydrogen environment embrittlement of sensitized austenitic stainless steels at low temperatures
TL;DR: In this paper, the effect of the strain-induced martensite, distinguished from that of the carbides, both existing along the grain boundaries in the sensitized materials, was examined.

A general mechanism of martensitic nucleation: Part II. FCC → BCC and other martensitic transformations
Gregory B. Olson,Morris Cohen +1 more
TL;DR: In this article, the general mechanism of martensitic nucleation by faulting from groups of existing dislocations, as proposed in Part I, is applied to the fcc → bcc, bcc → fcc, hcp → hcp, and related transformations, including mechanical twinning.
