Journal ArticleDOI
Effect of microstructure on the hydrogen trapping efficiency and hydrogen induced cracking of linepipe steel
TL;DR: In this paper, a modified ISO17081(2004) standard method is used to evaluate the hydrogen trapping by measuring the permeability (JssL) and apparent diffusivity (Dapp).
Journal ArticleDOI
Relationship between hydrogen-induced cracking and type I sulfide stress cracking of high-strength linepipe steel
TL;DR: In this article, the authors showed that HIC occurs as an initial crack of type I SSC, which is the same as a hydrogen-induced blister crack (HIBC), and thus the initial crack behavior of HIBC as a precursor to type I SSC can be evaluated by the cathodic hydrogen charging method.
Journal ArticleDOI
Effect of Microstructure on Hydrogen-Induced Cracking of Linepipe Steels
TL;DR: In this article, the effect of microstructure on HIC was discussed for steels having two different levels of nonmetallic inclusions, and it was shown that the minimum permissible inclusion level for HIC not to develop varied according to the steel micro-structure.
Hydrogen Diffusion And Trapping Behavior of Linepipe Steel Under Dead Weight Test Condition
TL;DR: In this article, the effect of constant elastic load on the hydrogen diffusion and trapping behavior of linepipe steel under NACE TM0177 A method was studied and shown that lattice expansion by elastic stress increases the solubility of hydrogen, while hydrogen diffusion becomes slow.
