Engineering thoughts on Hydrogen Embrittlement

Procedia Structural Integrity, 2018
Abstract Hydrogen Embrittlement (HE) is a topical issue for pipelines transporting sour products. Engineers need a simple and effective approach in materials selection at design stage. In other words, they must know if a material is susceptible to cracking, to be able of: selecting the right material and apply correct operational measures ...

Origin of deformation twins and their influence on hydrogen embrittlement in cold-rolled austenitic stainless steel

, 2021
The effect of cold rolling on hydrogen embrittlement in stable 18Cr-1Mn-11Ni-0.15 N austenitic stainless steels was investigated. Alloy plates were cold-rolled to 15% or 30% reduction, then pre-charged with hydrogen and subjected to tensile testing with ...

Embrittlement behaviour of metal additive-manufactured high-entropy alloy components under gaseous and electrochemical hydrogen charging

Journal of Materials Research and Technology
Embrittlement is an environmentally induced fracture that primarily affects metallic materials. This phenomenon occurs when hydrogen is absorbed on the metal surface and penetrates to the core, followed by degrading the mechanical properties in a ...

Hydrogen‐Assisted Fracture of Iron‐Based Fe–Ni–Al Alloys

Advanced Engineering Materials, EarlyView.
Principal relations and fracture mechanisms of single‐phase and precipitate‐strengthened Fe–Ni–Al alloys subjected to prior electrochemical hydrogen charging are identified. The mechanisms of hydrogen effect on strength and microhardness are discussed, including hydrogen‐induced increase in microhardness and the role of hydrogen in fracture behavior ...

Impact of hydrogen on the high cycle fatigue behaviour of Inconel 718 in asymmetric push–pull mode at room temperature

, 2015
The influence of hydrogen on the high cycle fatigue (HCF) behaviour of Inconel 718 has been studied at room temperature in asymmetric push–pull mode using an ultrasonic HCF test rig. Fatigue tests have been carried out in gaseous hydrogen (GH2) and in Ar

Functional and Network PHAs via Stereoselective Polymerization and Tailored Post‐Transformation

Angewandte Chemie, EarlyView.
Catalyst‐controlled stereoselective (co)polymerization of functionalized lactones produces vinyl‐, allyl‐, and propargyl‐functionalized PHAs with high syndiotacticity and a broad applicable temperature window, which can be further transformed into crosslinked PHA thermosets, elastic supramolecular networks, and functional grafts.
