Characterization of Irradiation and Environmental Effects in Metallic and Ceramic Materials
EMSL Project ID
50074
Abstract
This proposed work aims to provide samples from archive materials and highly radioactive materials to document the changes in metals and ceramics that have been subjected to neutron and/or ion irradiation, potentially under oxidizing environments. These samples will allow various characterization techniques to be used on small samples prepared from radioactive materials using FIB milling, which produces samples of such small volume that they can be free released as non-radioactive. This ability to produce such samples is critical to exploring the changes in microchemistry and microstructure at the atomic scale without interference from the radioactivity of the samples. The use of the atom probe and ETEM are required to explore atomistic changes that cannot be detected with other ex-situ instrumentation.
