Hydrogen-enhanced oxidation of ferrite phase in stainless steel cladding and the contribution to stress corrosion cracking in deaerated high temperature water
نویسندگان
چکیده
Oxide film properties and stress corrosion cracking (SCC) behaviour are investigated in the 308L stainless steel cladding layer with without being H-charged a deaerated high temperature water. Phase boundary (PB) has lower oxidation resistance than austenite ?-ferrite matrix. A compact Cr content-bearing inner oxide improves of phase H charging. H-induced PB penetration grain (GB) preferential observed specimen due to GB act as trapping sites. Charged decreases austenite. ?-Ferrite acts path for diffusing flux facilitates mass transport, resulting poor ?-ferrite. The mechanism underlying effect on behaviours austenitic phases, well SCC performance, discussed.

This article describes the susceptibility of 316L stainless steel to stress corrosion cracking (SCC) in a nitrite-containing chloride solution. Slow strain rate testing (SSRT) in 30 wt. % MgCl₂ solution established SCC susceptibility, as evidenced by post-SSRT fractography. Addition of nitrite to the chloride solution, which is reported to have inhibitive influence on corrosion of stainless ste...

In the present work, the mechanical behavior of stress corrosion cracking phenomenon is described. Such phenomenon presents strong complexity due to metallurgic and electrochemical aspects. A methodology for modeling both SSR (Slow Strain Rate) and CL (Constant Load) tests based upon thermodynamics of continuum solids and elastoplastic damage is proposed. In this macroscopic approach, besides t...
