May 01, 2008 · 3.2. The effect of martensitic transformation on hydrogen diffusion in austenitic stainless steels. Hydrogen diffusion in martensitic of ferritic stainless steels with BCC structure is much faster than that in austenitic stainless steels with FCC structure , .Therefore, hydrogen diffusion in a partially martensitic-transformed austenitic stainless steel is expected to be faster than in the Famous failures series:Part 2 hydrogen embrittlement Environmental hydrogen embrittlement can be caused by the external introduction of hydrogen while the bolt or anchor is under stress (Jones, 1996). Such environmental conditions can include (but are not limited to) the salinity of air or water vapour, leachates, admixtures, effluent or acidity of rainwater (Gangloff, 1986).

Forming-Induced Residual Stress and Material Properties of

Aug 14, 2020 · Martensitic steels are widely used in the automotive lightweight application but less understood in aspects of post-forming material properties. The steels show good ductility in roll forming but occasionally experience delayed (hydrogen) fracture issues, which are believed to be due to the formation of localized residual stress and a reduced product of strength and elongation. 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.
