Environmental Sensitivity of Structural Metals: Liquid Metal Embrittlement.
Abstract
The phenomenon of liquid metal embrittlement is being investigated on levels from the atomic through bulk specimen and structural properties, and is being considered from both experimental and theoretical viewpoints. The research is aimed at elucidating all three important aspects of LME, namely, the mechanism by which embrittlement takes place at a crack, or potential crack, site, the mechanism by which the embrittling species is transported to this site, and the various metallurgical, physical, and mechanical factors which have a significant influence on the severity of the embrittlement. The original proposal for this work included ten specific research topics. The progress on these since July, 1969 and also on an eleventh topic are listed. The first two topics are aimed primarily at an understanding of the transport mechanism in LME, the second five at the embrittlement mechanism itself, and the next three at mechanical and metallurgical factors influencing the embrittlement. The last topic is an attempt at a new theoretical approach to LME. (Author)
