Did you know?
Metal-induced embrittlement (MIE) is the embrittlement caused by diffusion of metal, either solid or liquid, into the base material. Metal induced embrittlement occurs when metals are in contact with low-melting point metals while under tensile stress. The embrittler can be either solid (SMIE) or liquid (liquid metal embrittlement). Under sufficient tensile stress, MIE failure occurs instantaneously at temperatures just above melting point. For temperatures below the melting te… Web@article{osti_5782922, title = {Semiempirical, quantum mechanical calculation of hydrogen embrittlement in metals}, author = {Daw, M S and Baskes, M I}, abstractNote = {A new, …
Web1 jul. 2024 · The crack path of an austenitic steel fracture induced by liquid mercury has been elucidated at microstructural scale. Deformation induced martensite (γ (fcc) → α’ (bcc)) of the low nickel steels induces numerous α’/α’ interfaces at small scale that are susceptible to be embrittled. Web24 mrt. 2024 · Liquid Metal Embrittlement (LME) is defined as a decrease in ductility of a solid metal in contact with a liquid metal. 1 There are specific couples of solid and liquid metals that have been known to cause such embrittling effects.
