TLDR
In this paper, a specimen of 75% Pd + 25% Ag alloy, saturated with hydrogen at 75°C and 102 torr H 2 pressure (H/Me = 0.32), was stressed elastically in uniaxial tension and compression.About:

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.

A linear theory of thermochemical equilibrium of solids under stress
Francis Larché,John W. Cahn +1 more
TL;DR: In this paper, a thermodynamic theory of stressed solids has been constructed, where the necessary equations for equilibrium can be separated into purely elastic and purely chemical equations, and all the parameters of these equations can be computed from standard measurements.
Journal ArticleDOI
Hydrogen related failure of steels – a new aspect
TL;DR: In this paper, the role of hydrogen in reducing ductile crack growth resistance is attributed to the increased creation of vacancies on straining, which is supported by a recent finding of amorphisation associated with crack growth.
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
Effects of alloy composition and strain hardening on tensile fracture of hydrogen-precharged type 316 stainless steels
TL;DR: The use of type 316 stainless steels in gaseous hydrogen infrastructure motivated the work on hydrogen-assisted fracture in this paper, where the tensile ductility of 316 stainless steel is reduced by internal hydrogen contents of 136 wppm that have been generated by thermal precharging in hydrogen gas.

The Thermodynamics of Stressed Solids
TL;DR: In this article, the existence of a chemical potential of a mobile component everywhere within a solid within a generalized stress system is demonstrated, as well as also the presence of an immobile component of a stressed body at appropriate interfaces.

Effect of Deformation on the Swelling Capacity of Rubber
Paul J. Flory,John Rehner +1 more
TL;DR: In this paper, it was shown that the relative volume of the swollen rubber at equilibrium should equal the square root of the relative stretched length, and that the size of the swelling agent should be proportional to the length of the stretched length.

The swelling of cross-linked amorphous polymers under strain
TL;DR: In this article, the equilibrium swelling of vulcanized natural rubber in benzene and heptane was investigated experimentally as a function of the state of strain, i.e., simple elongation, 2-dimensional extension, and unidirectional compression.
