Hydrogen Embrittlement in Super Duplex Stainless Steels
Nov 2019
Publication
In super duplex stainless steels (SDSSs) both austenite and ferrite are susceptible to hydrogen embrittlement however there is a lack of understanding into the effect of hydrogen in each phase. In this study in neutron diffraction was applied on hydrogen-charged (H-charged) samples to investigate the hydrogen embrittlement behaviour in super duplex stainless steels.

Eliminating CO2 emissions from industry and transport in line with the 1.5⁰C climate goalTo avoid catastrophic climate change the world needs to reach zero carbon dioxide (CO2) emissions in all all sectors of the economy by the 2050s. Effective energy decarbonisation presents a major challenge especially in key industry and transport sectors.The International Renewable Energy Agency (IRENA) has produced a comprehensive study of deep decarbonisation Read More
A Critical Review on the Principles, Applications, and Challenges of Waste-to-hydrogen Technologies
Sep 2020
Publication
Hydrogen sourced from energy recovery processes and conversion of waste materials is a method of providing both a clean fuel and a sustainable waste management alternative to landfill and incineration. The question is whether waste-to–hydrogen can become part of the zero-carbon future energy mix and serve as one of the cleaner hydrogen sources which is economically viable and environmentally friendly. This work critically assessed the potential Read More
Investigation of the Hydrogen Embrittlement Susceptibility of T24 Boiler Tubing in the Context of Stress Corrosion Cracking of its Welds
Dec 2018
Publication
For the membrane and spiral walls of the new USC boilers the advanced T24 material was developed. In 2010 however extensive T24 tube weld cracking during the commissioning phase of several newly built boilers was observed. As the dominant root cause Hydrogen Induced - Stress Corrosion Cracking was reported. An investigation into the interaction of the T24 material with hydrogen was launched in order to compare its hydrogen embrittlement su Read More
Tensile and Fatigue Properties of 17-4PH Martensitic Stainless Steels in Presence of Hydrogen
Dec 2019
Publication
Effects of hydrogen on slow-strain-rate tensile (SSRT) and fatigue-life properties of 17-4PH H1150 martensitic stainless steel having an ultimate tensile strength of ~1GPa were investigated. Smooth and circumferentially-notched axisymmetric specimens were used for the SSRT and fatigue-life tests respectively. The fatigue-life tests were done to investigate the hydrogen effect on fatigue crack growth (FCG) properties. The specimens tested in Read More
Tracking Hydrogen Embrittlement Using Short Fatigue Crack Behavior of Metals
Dec 2018
Publication
Understanding hydrogen embrittlement phenomenon that leads to deterioration of mechanical properties of metallic components is vital for applications involving hydrogen environment. Among these understanding the influence of hydrogen on the fatigue behaviour of metals is of great interest. Total fatigue life of a material can be divided into fatigue crack initiation and fatigue crack growth phase. While fatigue crack initiation can be linked with the pr Read More
Hydrogen Embrittlement in Pipelines Transporting Sour Hydrocarbons
Sep 2017
Publication
Lamination-like defects in pipeline steels can be of both metallurgical and operational origin. In pipelines transporting hydrocarbon usually such defects are not a big challenge since they do not propagate under operating conditions. Nonetheless in presence of a corrosion phenomenon and sour gas (H2S) it is possible to observe blisters and cracks which may propagate in the steel. The observed damage mechanisms is Hydrogen Embrittlement and in sp Read More
Effect of Deformation Microstructures on Hydrogen Embrittlement Sensitivity and Failure Mechanism of 304 Austenitic Stainless Steel: The Significant Role of Rolling Temperature
Feb 2022
Publication
Metastable austenitic stainless steels (ASSs) have excellent ductility but low strength so that their usage as load-bearing components is significantly limited. Rolling is an effective method of increasing strength whereas the effect of rolling temperature on microstructural evolution the hydrogen embrittlement (HE) sensitivity and fracture mechanisms is still unclear. In present study the effect of cold/warm rolling on detailed microstructural characteristics of 3 Read More

Critical Review of Models for H2-permeation Through Polymers with Focus on the Differential Pressure Method
May 2021
Publication
To reduce loss of hydrogen in storage vessels with high energy-to-weight-ratio new materials especially polymers have to be developed as barrier materials. Very established methods for characterization of barrier materials with permeation measurements are the time-lag and flow rate method along with the differential pressure method which resembles the nature of hydrogen vessel systems very well. Long measurement durations are necessary to gai Read More
