| Abstract Scope |
Micropillars of F/M steel HT9 were processed using Focused Ion Beam (FIB). The pillars were subject to 1.7 MeV Au3+ and/or implanted with 10 keV He+ at 470 °C in-situ in a TEM. After the in-situ irradiation, the pillars were then subject to compression tests at a displacement rate of 5 × 10-4 s-1 at room temperature using a pico-indenter in-situ in a TEM. Snapshots, video and stress-strain curve were recorded for each tested pillar. The changes in the microstructure were tracked during irradiation and during compression in-situ in the TEM to understand the radiation hardening due to radiation damage and the impact of the He bubbles in HT9. |
