Hydrogen permeation behavior and hydrogen-induced

Aug 01, 2020 · The 316L austenitic stainless steel (SS), due to its sufficient tolerance for corrosion and radioactivity, Hydrogen permeation behaviour in austenitic stainless steels. Mater. Sci.

Hydrogen permeation behavior and hydrogen-induced this work, we introduced H atoms into the selective laser melting (SLM) 316L stainless steel (SS) via two different H permeation methods and characterized its H permeation behavior and microstructure change. Results showed that the H diffusion rate in the SLM 316L SS was much higher than that in the cold-rolled (CR) one. The abundant

Dec 17, 2017 · Hydrogen permeation through several common stainless steels, as well as Inocnel and Hastelloy Though this result is about half of the previous at high temperature, I would trust it better, at least for annealed SS-304, and also for any annealed austenitic stainless steel. Interrogating the Effects of Hydrogen on the Behavior of Feb 27, 2021 · The effects of internal hydrogen on the deformation microstructures of 304L austenitic stainless steel have been characterized using electron backscattered diffraction (EBSD), transmission Kikuchi diffraction (TKD), high-resolution scanning transmission electron microscopy (HRSTEM), and nanoprobe diffraction.

  • AbstractIntroductionExperimentalEffect of Test TemperatureEffect of Applied StressEffect of SensitizationA Proposal For Transgranular Hydrogen Embrittlement MechanismAcknowledgmentThe stress corrosion cracking (SCC) and hydrogen embrittlement (HE) behaviors for types 304, 310, and 316 austenitic stainless steels were investigated in boiling saturated magnesium chloride solutions using a constant load method under different conditions including test temperature, applied stress, and sensitization. Both of type 304 and type 316 stainless steels showed quite similar behavior characteristics, whereas type 310 stainless steel showed a different behavior. The time to failure () parPermeation of multi-component hydrogen isotopes through However, the permeation of multi-component hydrogen isotopes through austenitic stainless steels has not been discussed so far. In this paper the permeation behavior of hydrogen isotopes through type 304 and 316 austenitic stainless steels was investigated by the co-current double tube method in the temperature range of 623-973 K.

    precipitation in austenitic alloys has been linked to chromium depletion in adjacent areas. Regions poor in carbon and chromium are prone to strain-induced martensitic transformations and may be active hydrogen trapping sites. The role of martensite on hydrogen embrittlement in austenitic stainless steels has not been firmly established.Hydrogen permeation behaviour in austenitic stainless steelsTranslate this pageHydrogen permeation behaviour in austenitic stainless steels The permeability, diffusivity and solubility of hydrogen in six types of austenitic stainless steel316L, 316LN, 21-69, 21-9-9, 304 and 321have been measured by a gaseous permeation technique in the temperature range 200430°C.
