Seminar by Dr. David Simeone

Dr. David Simeone
CEA, France

 

Abstract:

We will show the difficulties encountered by phase-field methods to describe the evolution of materials under irradiation. After a brief theoretical review of phase-field methods, we present the difficulties inherent in their use under irradiation. In particular, we introduce the Swift-Hohenberg equation to describe damage induced by ion irradiation, and discuss the notion of phase diagrams under irradiation. Finally, we give a brief overview of our work on FeCr samples irradiated with ions and electrons.

Seminar

Bio:

Dr. Simeone has been working for over 30 years at CEA on irradiation damage in materials and its impact on microstructure and mechanical properties.  After developing grazing-incidence X-ray diffraction techniques to measure irradiation-induced microstructures and co-developing the DART code with Dr. Luneville, he has since been working on phase-field methods to predict the evolution of material microstructures under and outside irradiation.
