Liquid Metal Embrittlement, chapitre 22

Abstract

If the terminology “hydrogen embrittlement” (HE) very explicitly points to the species responsible for the physical phenomenon, it is not the same for liquid metal embrittlement (LME). Whilst the first case suggests focusing on the presence of H+, H or H2, the second suggests that a priori all metals, provided that they are liquid, could lead to ductility loss. However, in terms of the literature, the number of articles dedicated to LME is much more modest than that dedicated to HE and accordingly the phenomena and the cases of LME are certainly less well known than those of HE.
