| Abstract | Examination of deformation microstructures induced by micro-indentation technique by means of transmission electron microscopy following an MV range metallic ion irradiation was performed in order to study the influence of irradiation-produced microstructural de-fects on plastic deformation behavior of materials. In this work, specimens of an Fe-Cr-Ni austenitic model ternary alloy before and after irradiation with 4 MeV Ni ions at 723K were indentation-tested at loads as low as 9.8 mN using an instrumented micro-indentation testing system. The dislocation microstructures of the specimens ’ regions beneath the indents were successfully examined with a transmission electron microscopy following a cross-sectional thin lm processing with a focused ion beam (FIB) processing system. This paper describes the experimental procedure developed in this study and the results from the rst series of the experiments. 1 |
