Abstract

The work reported herein is a continuation of studies into the detection and characterization of grain boundaries which have become enriched by the accumulation of undesirable elements or second-phase precipitates. These conditions have been associated with embrittlement in several alloys, and may radically alter engineering properties of the bulk material. Grain boundaries can become enriched, or decorated, during heat treatments, including welding, associated with fabrication or in-service repair. Additionally, embrittlement can occur during the service life of components exposed to intense radiation.
