Hydrogen solubility, diffusivity, and trapping in quenched and tempered Ni-containing steels
(Elsevier, 2022-01)
Hydrogen permeation experiments were performed in quenched and tempered (Q&T) low alloy steels with varying Ni contents exposed to 1 bar H2 at 30, 50 and 70 °C. From the analysis of build-up and decay transients, it is ...
Comparative study of Fe-C-H interaction near line and point defects in iron structures
(World Scientific, 2008-06)
The FeCH interaction near defects in iron structures was studied using qualitative structure calculations in the framework of the atom superposition and electron delocalization molecular orbital. Calculations were performed ...
Relationship between hydrogen embrittlement and Md30 temperature: Prediction of low-nickel austenitic stainless steel's resistance
(Pergamon-Elsevier Science Ltd, 2019-09)
Hydrogen embrittlement (HE) of several low-nickel austenitic stainless steels (AISI 300 series) was studied with special attention to the impact of strain induced α′-martensite. The susceptibility of the steels to HE is ...
Effect of nickel on hydrogen permeation in ferritic/pearlitic low alloy steels
(Pergamon-Elsevier Science Ltd, 2018-02)
Nickel offers several beneficial effects as an alloying element to low alloy steels. However, it is, in the oil and gas industry, limited by part 2 of the ISO 15156 standard to a maximum of 1 wt% due to sulfide stress ...
Influence of hydrogen on the microstructure and fracture toughness of friction stir welded plates of API 5L X80 pipeline steel
(2019-08-30)
In this work, the influence of hydrogen on the microstructure and fracture toughness of API 5L X80 high strength pipeline steel welded by friction stir welding was assessed. Samples were hydrogenated at room temperature ...
The influence of microstructure on the hydrogen embrittlement in martensitic-ferritic stainless steel
(Universidade Federal de Minas GeraisUFMG, 2015-10-29)
This work investigates the interaction of hydrogen with the microstructure in the martensitic-ferritic stainless steel (MFSS). The samples were extracted from hot rolled seamless stainless steel tube after a solution ...
