Microstructures and Precipitates in Ion-implanted Energy Materials
EMSL Project ID
48707
Abstract
A project from the fusion materials program at PNNL, sponsored by DOE Office of Science FES (Fusion Energy Science), will be carried out under this EMSL general user proposal for FY15. The experimental studies will focus on the scientific issues associated with microstructures and precipitates of the energy materials under extreme conditions (high radiation and high temperature). Ion implantation will be used as an accelerated aging approach to simulate the irradiated microstructure and introduce transmutants or their surrogates in the structure for study. The work scope will include ion-beam irradiation induced disordering processes in ceramic materials, in-situ study of nanostructural evolution, thermal and dynamic recoveries of defects, roles of interfaces, trapping and clustering of defects and implanted species, atomic diffusion, and precipitation of fusion transmutants or their surrogates. The primary objective of the research is to advance the fundamental understanding of irradiation effects on the microstructures and physical/chemical properties of fusion materials. The research is aligned with the US national strategic plan for clean and sustainable energy, and supports DOE missions on development of new reactors to enable nuclear energy to help meet the nation’s energy security and climate change goals.
