Environmental Sensitivity of Structural Metals: Liquid Metal Embrittlement
ILLINOIS INST OF TECH CHICAGO
The report considers liquid metal embrittlement LME. The phenomenon of LME 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 the 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. Eleven specific investigations are underway in various stages of progress, with the first two topics aimed primarily at an understanding of the transport mechanism in LME, the second five at the embrittlement mechanism, and the next three at mechanical and metallurgical factors influencing the embrittlement. The last topic is an effort at a new theoretical approach to LME.
