Modeling failure of metallic glasses due to hydrogen embrittlement in the absence of external loads
A model is developed to describe the expansion of high-pressure hydrogen bubbles and propagation of cracks between them in the absence of external loads. The focus is on cracks that form during electrochemical hydrogen charging of amorphous Fe80B11Si9 ribbons. A coupled diffusion/fracture mechanics approach is developed, allowing determination of the time to failure. Finite element analyses are...
متن کاملPrevention of Hydrogen Embrittlement in Steels
The essential facts about the nature of the hydrogen embrittlement of steels have now been known for 140 years. It is diffusible hydrogen that is harmful to the toughness of iron. It follows, therefore, that the harmful influence of diffusible hydrogen can be mitigated by preventing its entry into steel or by rendering it immobile once it penetrates the material. This review deals with the meth...
متن کاملStudy on Temper Embrittlement and Hydrogen Embrittlement of a Hydrogenation Reactor by Small Punch Test
The study on temper embrittlement and hydrogen embrittlement of a test block from a 3Cr1Mo1/4V hydrogenation reactor after ten years of service was carried out by small punch test (SPT) at different temperatures. The SPT fracture energy Esp (derived from integrating the load-displacement curve) divided by the maximum load (Fm) of SPT was used to fit the Esp/Fm versus-temperature curve to determ...
متن کاملCharacteristics 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 کاملPitting-induced hydrogen embrittlement of magnesium- aluminium alloy
In this study, the pitting corrosion susceptibility and its role on the hydrogen embrittlement behavior of AZ80 magnesium alloy were studied using slow strain rate testing (SSRT), electrochemical technique and immersion test method. The electrochemical and immersion tests in chloride-containing solution revealed severe pitting corrosion in the alloy. The SSRT results of the alloy under continuo...
