Hydrogen-induced cracking was investigated by TEM in-situ tension in hydrogenated stainless steel of type 310. It was found experimentally that hydrogen-induced cracking happens via nanovoid nucleation followed by quasi-cleavage along {111} planes when C H is higher. Otherwise, in the case of ...
Stress corrosion cracking(SCC) and hydrogen induced cracking(HIC) of Type 321 stainless steel under mode Ⅱ loading were investigated with notched specimens. Experimental results showed that SCC in boiling 42% MgCl_2 solution initiated at the maximum normal stress site, i. e., at= -110° on ...
Both 22Cr and 25Cr duplex (ferritic-austenitic) stainless steels have been extensively used for subsea equipment. In general the experience is good but some significant failures have occurred where Hydrogen Induced Stress Cracking (HISC) have been identified as a contributing factor. Because of thes...
Hydrogen stress cracking, often referred to as hydrogen-induced cracking or static fatigue, is characterized by the brittle fracture of a normally ductile alloy under sustained load in the presence of hydrogen. From: Oil and Gas Corrosion Prevention, 2014 ...

This work aims to study the hydrogen-induced delayed cracking related to the martensitic transformation in the AISI 301 unstable austenitic stainless steel. It happens because the metastable austenite is substantially transformed into α-martensite due to the deformation occurring during the clamp-forming...
1)hydrogen induced cracking氢致开裂 1.Thehydrogen induced cracking(HIC) of X70 pipeline steel was studied in H2SO4 solutions with different concentrations by means of electrochemical charging.采用电化学充氢的方法研究了X70管线钢在不同浓度硫酸溶液中的氢致开裂(HIC)行为。
6) hydrogen-induced cracking 氢致开裂 1. The threshold stress intensity of hydrogen-induced cracking during dynamical charging for 40CrMo steel decreased linearly with the logarithm of the concentration of diffusible hydrogen, C0, i. 动态充氢时氢致开裂(HIC)门槛应力强度因子KIH随试样中可扩散氢浓度...
The role of hydrogen in stress-corrosion cracking (SCC) of austenitic stainless steel was investigated in boiling chloride solution. The tests in the mixed melted salt verified that hydrogen-induced cracking (HIC) could occur at 160 °C if sufficient hydrogen could be supplied continuously. It was...
