Embrittlement of case hardened steel chain link
(PERGAMON-ELSEVIER SCIENCE LTD, 2009)
Various steel chain links presented cracking during their manufacturing process, which includes induction case hardening and electrogalvanizing steps. Fractographic examination of the exposed crack surfaces revealed ...
Corrosion behavior of api 5l x70 carbon steels in hydrogen sulfide environments
(2021-01-01)
As we all know, corrosion of pipelines by hydrogen sulfide is the most worrying factor in the production and transport of oil and gas. In this work the corrosion behavior of API 5L X70MS and X70MO low carbon steels in ...
Influence of Microstructures on Polarization Resistance and Hydrogen-Induced Cracking of a Micro-Alloyed Steel Submitted to Different Cooling Rates
(JOURNAL IRON STEEL RESEARCH EDITORIAL BOARD, 2011)
The effect of different microstructures on the polarization resistance (Rp) and the hydrogen-induced cracking (HIC) of a micro-alloyed steel austenitized and submitted to different cooling rates was studied. Samples 19.1 ...
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 ...
Effect of dilute H on crack tip plasticity in Zr
(Elsevier Science, 2013-03)
We studied the plasticity mechanisms that occur near a crack tip in hcp Zr with dilute amounts of interstitial H impurities. A quasi-static method was used to simulate crack propagation and the atomic interactions were ...
