چکیده
We present a phase field-based electro-chemo-mechanical formulation for modelling mechanics-enhanced corrosion and hydrogen-assisted cracking in elastic–plastic solids. A multi-phase-field approach is used to present, the first time, general framework stress cracking, incorporating both anodic dissolution hydrogen embrittlement mechanisms. numerically implement our theory using finite element method defining as primary fields displacement components, field order parameter, metal ion concentration, fracture parameter concentration. Representative case studies are addressed showcase predictive capabilities of model various materials environments, attaining promising agreement with benchmark tests experimental observations. show that generalised presented can capture, function environment, interplay between dissolution- hydrogen-driven failure mechanisms; including transition from one other, their synergistic action individual occurrence. Such bring new insight into environment–material interactions understanding demonstrated here by providing simulation results Gruhl’s seminal experiments.

Characteristics of Hydrogen Embrittlement, Stress Corrosion Cracking and Tempered Martensite Embrittlement in High-strength Steels
Characteristics of tempered martensite embrittlement (TME), hydrogen embrittlement (HE), and stress corrosion cracking (SCC) in high-strength steels are reviewed. Often, it is important to determine unambiguously by which of these mechanisms failure occurred, in order to suggest the right actions to prevent failure recurrence. To this aim, samples made of high-strength AISI 4340 alloy steel wer...
متن کاملA Comparison of Hydrogen Embrittlement and Stress Corrosion Cracking in High Strength Steels
The purpose of this study was to compare the known behavior of hydrogen embrittled high-strength steel to the characteristics of environmentallyinduced stress corrosion failure where hydrogen is continuously generated at the specimen surface. The incubation time for the initiation of slow crack growth was accelerated by prestressing for a fixed time below the lower critical limit. These results...

متن کاملEffect of Hydrogen on Corrosion and Stress Corrosion Cracking of AZ91 Alloy in Aqueous Solutions
The effect of hydrogen on the corrosion and stress corrosion cracking of the magnesium AZ91 alloy has been investigated in aqueous solutions. Hydrogen produced by corrosion in water diffuses into, and reacts with the Mg matrix to form hydride. Some of the hydrogen accumulates at hydride/Mg matrix (or secondary phase) interfaces as a consequence of slow hydride formation and the incompatibility ...
