Abstract Scope |
High entropy alloys (HEAs) and other compositionally complex alloys (CCAs) are being engineered to meet the unique requirements of advanced nuclear applications. Specific to fusion and fast fission reactors, reactor core materials must withstand high fluxes of high energy neutrons, resulting in high levels of radiation induced damage and transmutation which can deleteriously impact material properties. In addition, for future commercial fusion reactors, materials are expected to meet the reduced activation criterion, designed to not be radioactive for more than 100 years following removal from the reactor core. In this talk, an overview of our alloy design process, used to target reduced activation compositions which are predicted to be radiation damage resistant, will be given. Examples of our experimental assessments of the suitability of these alloys for advanced nuclear applications, including using in-situ high temperature X-ray diffraction, and ion implantation to simulate neutron irradiation and transmutation products, will be presented. |
