Metal-Induced embrittlement of metals—an evaluation of embrittler transport mechanisms

  • Paul Gordon

Abstract

An analysis is made of the possible embrittler transport mechanisms in liquid metal-induced embrittlement (LMIE) and solid metal-induced embrittlement (SMIE). The analy-sis and comparison with experiments makes it appear likely that a) in LMIE bulk liquid flow is the transport mechanism; liquid metals which “wet” the base metalcan penetrate to the tips of even very sharp cracks, contrary to some statements in the literature; b) in SMIE surface self-diffusion of the embrittler is the transport mechanism; and c) vapor transport could play a role for a few high-vapor pressure embrittlers—such as Zn, Cd, and possibly Hg—but is not a viable transport mechanism for most embrittlers.
