Hydrogen is considered a clean and efficient energy carrier crucial for shaping the net-zero
future. Large-scale production, transportation, storage, and use of green hydrogen are …

Conventional-sized specimens have been well and widely applied in research on hydrogen
embrittlement. However, when the limited-size core components (nozzles and valves, etc.) of …

Susceptibility to hydrogen embrittlement was studied on quenched and tempered 42CrMo
steel with Small Punch Tests (SPT) using different punch displacement rates. Hydrogen was …

This paper presents a simulation method for combined ductile–brittle fracture of small punch
(SP) test in hydrogen and application to test data of API X70 steel. For ductile fracture …

Recently, as hydrogen has been increasingly applied in the field of new energy, it has
become necessary to evaluate the mechanical characteristics of hydrogen embrittlement …

Electrochemical and gaseous hydrogen precharging are representative methods for
evaluating hydrogen embrittlement in metallic materials. In this study, the effects of these …

In this paper, we propose a numerical methodology to predict the effect of hydrogen
concentration on fracture toughness by using small punch (SP) test data in hydrogen. The …

The presence of microstructural heterogeneity within welded joints, combined with
environmental factors, can have detrimental effects on the service life of engineering …

In this study, the hydrogen embrittlement (HE) behavior confined to focusing the weld
microstructure of austenitic stainless steels (ER308 and ER316) was investigated. To …

This study investigates the effect of a hydrogen/natural gas mixture on the mechanical
properties of API X42 pipeline steel using small punch (SP) test. The hydrogen-assisted …
