Meeting 2018 TMS Annual Meeting & Exhibition
Symposium Thermal and Mechanical Stability of Nanocrystalline Materials
Presentation Title Irradiation Creep in Nanostructures Measured Using In-situ TEM
Author(s) Shen J Dillon, Khalid Hattar
On-Site Speaker (Planned) Shen J Dillon
Abstract Scope Nanostructured alloys are envisioned as potential next-generation nuclear materials. However, little is known about the mechanisms for irradiation induced creep (IIC) in nanostructured materials. While traditional mechanisms for IIC may be suppress in nanostructured alloys, new mechanisms for IIC could be activated and present unanticipated engineering challenges. Simulating neutron damage with ions in accelerated tests is challenging and ideally requires sub-micron scale samples. This talk reports on recent efforts to perform IIC using a combination of in-situ mechanical loading, ion irradiation, and laser heating in the transmission electron (I3TEM) at Sandia National Laboratories.
