Alloy and composition dependence of hydrogen embrittlement

Jun 12, 2017 · (a) General description of hydrogen embrittlement in high-strength steel Hydrogen embrittlement (HE) causes loss of ductility and, consequently, a loss of strength. HE in high-strength steel is described as permanent loss of ductility in a metal or alloy caused by atomic hydrogen in combination with load-induced and/or residual tensile stress Embrittlement of 4130 steel by low-pressure gaseous hydrogenA study has been made of the embrittlement of fully hardened 4130 steel in low-pressure, <760 torr, gaseous hydrogen. It was found that the embrittlement was caused by hydrogen-induced, slow crack growth. In the range of temperature from 80° to 25°C, the crack growth rate increased with decrease in temperature; in the range from 0° to 80°C, the rate decreased with decrease in temperature. Enhancing the hydrogen embrittlement resistance of 304 Abstract Grain boundary engineering has been widely applied to improve grain boundary-related properties such as intergranular corrosion, radiation damage and

Enhancing the hydrogen embrittlement resistance of 304

Abstract Grain boundary engineering has been widely applied to improve grain boundary-related properties such as intergranular corrosion, radiation damage and Figure 12 from Hydrogen embrittlement of ferritic steels Hydrogen embrittlement associated with strain localization in a precipitation-hardened FeMnAlC light weight austenitic steel M. Koyama , H. Springer , S. V. Merzlikin , Hydrogen Embrittlement - NACEHydrogen Embrittlement. This is a type of deterioration which can be linked to corrosion and corrosion-control processes. It involves the ingress of hydrogen into a component, an event that can seriously reduce the ductility and load-bearing capacity, cause cracking and catastrophic brittle failures at stresses below the yield stress of susceptible materials.

Hydrogen Embrittlement Understood SpringerLink

Mar 28, 2015 · Johnson, in 1875, launched the field of study of hydrogen embrittlement of metals with the publication of his observations of the influence of immersing a piece of iron in different acids on the mechanical properties.[] He summarized the macroscale effect as:After a few minutes immersion (half a minute will sometimes suffice) in strong hydrochloric or dilute sulfuric acida piece Hydrogen Embrittlement of Hardened Low-carbon 10B22 steel used for the earlier study of the mechanical Hydrogen Embrittlement of Hardened Low-carbon Sheet Steel Seok-Jae LEE, Joseph A.

Hydrogen embrittlement behavior of 13Cr-5Ni-2Mo

Nov 01, 2020 · This work presents a comprehensive study of the hydrogen embrittlement (HE) behavior of a 13Cr-5Ni-2Mo supermartensitic stainless steel through two aspects:hydrogen diffusion and hydrogen concentration. Precipitated austenite reduced the effective hydrogen diffusion coefficient and hydrogen permeation flux, and thus increased the HE resistance.

Hydrogen embrittlement in power plant steels Semantic In power plants, several major components such as steam generator tubes, boilers, steam/water pipe lines, water box of condensers and the other auxiliary components like bolts, nuts, screws fasteners and supporting assemblies are commonly fabricated from plain carbon steels, as well as low and high alloy steels. These components often fail catastrophically due to hydrogen embrittlement.

In power plants, several major components such as steam generator tubes, boilers, steam/water pipe lines, water box of condensers and the other auxiliary components like bolts, nuts, screws fasteners and supporting assemblies are commonly fabricated from plain carbon steels, as well as low and high alloy steels. These components often fail catastrophically due to hydrogen embrittlement. Prevention of Hydrogen Embrittlement in SteelsPrevention of Hydrogen Embrittlement in Steels H. K. D. H. Bhadeshiaa aMaterials Science and Metallurgy, University of Cambridge,U.K Abstract The essential facts about the nature of the hydrogen embrittlement of steels have now been known for 140 years. It is diusible hydrogen that is harmful to the toughness of iron. Study on Susceptibility of Hydrogen Embrittlement in a Susceptibility of hydrogen embrittlement of a super grade AISI 420 tool steel was studied. Tensile samples were cathodically charged to different hydrogen level. Hydrogen induced mechanical property degradation was measured by tensile tests at a low strain rate. Fractography of broken surfaces was observed using SEM. Relationship between hydrogen content and tensile strength and elongation

Investigation of hydrogen embrittlement in 12Cr2Mo1R(H)

Sep 24, 2018 · The hydrogen embrittlement of 12Cr2Mo1R(H) steel at different strain rates were investigated after hydrogen precharging for 4 h in a 0.5 M H 2 SO 4 solution with 2 g/L ammonium thiocyanate. Results showed that the embrittlement index increased and gradually reached a relative stable value of about 20% at the strain rate of 5 × 10 5 s 1 with the decrease of strain rates.
