Abstract

Liquid metal embrittlement is the cause of reduction of elongation to failure and early fracture if normally ductile metals or alloys are stressed while in contact with liquid metals. Scientists have confirmed that many solid steel-liquid metal couples are subject to liquid metal embrittlement, one of them is solid steel-liquid zinc. Due to the wide use of zinc-coated galvanized steels, this couple has drawn much attention. This paper briefly introduces liquid metal embrittlement, with emphasis on the solid steel-liquid zinc couple and its occurrence in the process of industrial production in the literature. We first reviewed the findings that galvanized steels suffer embrittlement during experimental hot tensile test to understand its fundamental characteristics. We then summarized the occurrence of liquid metal embrittlement in galvanized steels during industrial processing, such as hot-dip galvanizing, hot stamping and welding.
