Tensile Armor Wires Submitted to Slow Strain Rate Tests in a Corrosive Environment and Cathodic Protection: a Comparison Between Two Different Microstructures [PDF]

Materials Research, 2019
Tensile armor in flexible pipes consists of two or more layers of steel wires. Damage to the outer sheath may cause ingress of seawater in the annular space and thus corrosion of the armor wires.

Modified Slow-Strain-Rate Tensile Testing Method for Evaluation of Room-temperature Hydrogen Embrittlement Susceptibility and Its Application to 23Cr2Ni4MoV Steel

Chinese Journal of Mechanical Engineering
To evaluate the room-temperature hydrogen embrittlement susceptibility (HES) of high-pressure hydrogen storage vessels, a modified slow-strain-rate tensile (MSSRT) testing method was proposed for effectively aligning with their actual operating ...

New high concentration–high temperature hydrogenation method for slow strain rate tensile tests

Materials Letters, 2007
Abstract The aim of the present paper is to propose an innovative hydrogenation method based on metal hydride dissociation. By heating metal hydride, high pressure of molecular hydrogen is generated, which can be used to promote diffusion through the steel, resulting in very high atomic hydrogen concentration.

Finite difference modelling for understanding the hydrogen assisted cracking in virtual slow strain rate tensile tests

, 2021
Different hydrogen-induced cracking patterns have been observed on two construction steels belonging to the same strength grade for mooring offshore structures, when tested in a Slow Strain Rate Tensile test (SSRT) condition. A scenario is hypothesized, in which this behaviour arises from differences in hydrogen trapping capacity between the two steels.

Slow strain rate tensile tests on irradiated austenitic stainless steels in simulated light water reactor environments [PDF]

Nuclear Engineering and Design, 2014
Abstract Irradiation stress corrosion cracking (IASCC) is a critical degradation mechanism for reactor internal components that contributes to the safe and economic operation of reactors. As nuclear power plants age and irradiation dose increases, IASCC becomes an increasingly important issue because of its potential impact on the integrity of ...
