e/Liquid metal embrittlement

Information
has gloss	eng: Liquid metal embrittlement is a phenomenon of practical importance, where certain ductile metals experience drastic loss in tensile ductility or undergo brittle fracture when tested in the presence of specific liquid metals. Generally, a tensile stress, either externally applied or internally present, is needed to induce embrittlement. Exceptions to this rule have been observed, as in the case of aluminium in the presence of liquid gallium. People have studied this phenomenon from the beginning of the 20th century. Many of its phenomenological characteristics are known and several mechanisms were proposed to explain it. The practical significance of liquid metal embrittlement is revealed by the observation that several steels experienced ductility losses and cracking during hot dip galvanizing or during subsequent fabrication.
