Abstract
The present study investigated strain-rate sensitivity (SRS) of a single crystal Fe-15Cr-20Ni austenitic steel before and after 10.5 MeV Fe3+ ion-irradiation up to 10 dpa at 300 °C using a strain-rate jump (SRJ) nanoindentation test. It was found that the SRJ nanoindentation test is suitable for evaluating the SRS at strain-rates from 0.001 to 0.2 sâ1. Indentation size effect was observed for depth dependence of nanoindentation hardness but not the SRS. The ion-irradiation increased the hardness at the shallow depth region but decreased the SRS slightly.
