Irradiation resistant materials for extreme environments

Abstract 

The strategy for developing radiation resistant materials has long been recognized: introduce high concentrations of traps and unbiased sinks into the microstructure to enhance recombination and bubble nucleation. While these methods have been attempted in the past, they suffer from the fact that such nanostructured materials are generally unstable under irradiation. Nevertheless, progress is being made in developing new nanostructures materials that are showing remarkable stability. In this lecture, I will discuss these various directions, with emphasis on work at Illinois that explores immiscible alloys that self organize under irradiation. I will also discuss how these materials might be processed using the similar concepts of self organization during severe plastic deformation.

Brief Bio

Professor Averback received his PhD in physics at Michigan State University. He became interested ion-solid interactions and radiation damage while a postdoctoral fellow at Cornell University. He was a staff physicist at Argonne National Laboratory for 13 years, before joining the faculty as Professor at the University of Illinois in 1987. Professor Averback spent one year as a guest scientist at the Forschungszentrum Jülich on a Humboldt Award in 1993. His recent research concerns irradiation effects, severe plastic deformation and nanocrystalline materials.
