Kelle Embrittlement of ductile structural members, whether under the presence of static or cyclic loading, can occur when surrounded by a corrosive environment. Several examples of catastrophic failures due to a form of environmentally assiste...
متن کاملThe role of a bilayer interfacial phase on liquid metal embrittlement.
Intrinsically ductile metals are prone to catastrophic failure when exposed to certain liquid metals, but the atomic-level mechanism for this effect is not fully understood. We characterized a model system, a nickel sample infused with bismuth atoms, by using aberration-corrected scanning transmission electron microscopy and observed a bilayer interfacial phase that is the underlying cause of e...
متن کاملA Simple Evaluation of Grain Boundary Diffusion in Liquid Metal Embrittlement
Most works on liquid metal embrittlement up to 1960 are compiled by Rostoker et al. (1) They stated that grain boundary diffusion is not an origin of embrittlement, since its rate, in general, is too small. However, Waterhouse et al. (2), performing the experiment on 70/30 brass wetted with mercury, suggested that dissolution of zinc from grain-boundaries into mercury accelerates the degree of ...
متن کاملEmbrittlement of metal by solute segregation-induced amorphization.
Impurities segregated to grain boundaries of a material essentially alter its fracture behavior. A prime example is sulfur segregation-induced embrittlement of nickel, where an observed relation between sulfur-induced amorphization of grain boundaries and embrittlement remains unexplained. Here, 48x10(6)-atom reactive-force-field molecular dynamics simulations provide the missing link. Namely, ...
متن کاملMicrowave embrittlement
Mikrovlnné žiarenie frekvencie 2,45 GHz bolo použité na vzorkách uhlia z rôznych anglických lokalit, na ich tepelnú predúpravu pred rozpojovaním. Získané údaje poukazujú na vplyv mikrovlnnej tepelnej úpravy na relatívnu meliteľnosť uhlia. Výrazná redukcia ( 20 –40 % ) relatívnej energie mletia bola zaznamenaná už po pomerne krátkom čase pôsobenia mikrovlnného žiarenia (3 –8 min). Vplyv mikrovln...
