Hydrogen embrittlement of a Fe-Cr-Ni alloy: Analysis of the physical and chemical processes in the early stage of stress corrosion cracking initiation
(Elsevier, 2013-01)
The interaction of two-hydrogen atoms in a zone of g-Fe55Cr25Ni20 alloy having a vacancy (V) was studied by the atom superposition and electron delocalization molecular orbital (ASED-MO) method. The impurities are located ...
A comparative study of hydrogen-induced crackingresistances of API 5L B and X52MS carbon steels
(2019-01-01)
Susceptibility to hydrogen-induced cracking of API 5L B and X52MS low-carbon steels inNACE 177-A, 177-B and 284-B solutions has been investigated by the present work. A met-allographic analysis of these steels was performed ...
A THERMODINAMIC CORROSION STUDY OF CARBON STEELS IN HYDROGEN SULFIDE - EXPLORING CHEMICAL EQUILIBRIUM CONCEPTS
(Soc Brasileira Quimica, 2018-05-01)
This study addresses an inherent problem to the oil and natural gas exploration and production industry, the corrosion of pipes and tanks by H2S. H2S with water emulsified in the oil or H2S with the water vapor mixed in ...
Effects of welding procedure on corrosion resistance and hydrogen embrittlement of supermartensitic stainless steel deposits
(Elsevier, 2013-12)
The effects of shielding gas and post weld heat treatment on the pitting resistance, stress corrosion cracking and hydrogen embrittlement of supermartensitic stainless steel deposits were studied. Two all-weld-metal test ...
Hydrogen effects on the low cycle fatigue of high strength steels
(Taylor & Francis, 2014-04)
Hydrogen absorption occurs during steelmaking processes and causes detriment on mechanical properties, such as plasticity, fatigue strength and tensile strength, among others. The main purpose of the present paper is to ...
