In order to evaluate the influence of microstructure on hydrogen diffusion, electrochemical permeation test was used with different metallurgical states of the material, being as received both Influence of internal hydrogen content on the evolved May 25, 2021 · Request PDF Influence of internal hydrogen content on the evolved microstructure beneath fatigue striations in 316L austenitic stainless steel The effect of internal hydrogen
In this study, the influence of microstructure on hydrogen-induced cracking behavior of the duplex stainless-steel weld metal was investigated. Duplex stainless-steel weld metal specimens were prepared and slow strain rate tensile test was performed after hydrogen charging. The Role of Microstructure in Hydrogen-Induced Fatigue Sep 08, 2020 · There is less understanding of the influence of hydrogen on the microstructure generated during the plastic deformation that proceeds fracture on the fracture mode, fracture path, fatigue crack growth rate, etc. This is somewhat surprising as most if not all pure metals and their alloys exhibit extensive plastic deformation prior to failure.The Influence of Microstructure on Hydrogen Diffusion and The influence of microstructure on hydrogen diffusion and embrittlement of multiphase fine- grained structural steels with increased plasticity and strength was studied with electrochemical experiments which provide the hydrogenation of specimens in conditions simulating practice requirements.
