Recent developments in liquid-metal embrittlement
Author and Affiliation:
Stoloff, N. S.(Rensselaer Polytechnic, Institute, Troy, N.Y., United States)
Abstract: The paper reviews developments in liquid-metal embrittlement of the past 7 years including data on cyclic loading. Embrittlement by solid and liquid metals and by hydrogen has many common features, although the mechanism of embrittler transport differs. Fracture may occur in each type of embrittlement by environmentally assisted shear and by reduced cohesion; embrittlement under cyclic loading has been widely observed, with stress level, temperature, and substrate alloy composition and grain size being the major variables. The degree of embrittlement between any combination of environment (i.e. hydrogen, liquid metal, or solid metal) and substrate depends upon the strength of the interaction with the substrate, the kinetics of embrittler transport, the mutual solubility of embrittler and substrate, and a large number of test and microstructural conditions. A method of calculating the most significant of these variables and the strength of interaction was reviewed and predictions of embrittlement in previously untested couples were made.
