| Abstract Scope |
Nanomechanical tests are already being used to investigate material properties at very small scales. Such testing of irradiated nuclear materials can provide information as part of Post Irradiation Examination (PIE) as well as properties linked to manufacture, processing and use. Such testing may be used to evaluate samples so small that radiation levels fall below critical thresholds, or may be used to simulate localized failure in the microstructure.
Such measurements can provide a wide range of different mechanical properties by taking advantage of focused ion beam milled geometries. This talk will focus on the most recent developments in instrumentation for in-situ extreme mechanics testing at the micro and nanoscales, with specific focus on a testing platform capable of strain rate testing over the range 0.0001/s up to 10’000/s (8 orders of magnitude) and temperature range -150 to 1000 °C.
Apparatus modifications required for testing of radioactive materials will be presented. |
