The liquid metal embrittlement is a combined effect of solid metal surface attacked by _________

The liquid metal embrittlement is a combined effect of solid metal surface attacked by _________ Correct Answer low melting point metal

The molten metal embrittlement results when the solid surface of the metal is wetted by the lower melting point metal. For example, brass 70-30 fails in an intergranular brittle fracture when wetted by mercury.
