Abstract

Characterization of the plastic deformation properties of thin damaged layers produced by heavy ion beam in an MeV energy range is being attempted by mean of a very low load indentation technique. This paper focuses on the development of experimental techniques and special considerations in analyzing the measured data from specimens which possess perpendicularly uneven hardness property. For this purpose, metals and alloys of different classes, namely a model austenitic alloy, pure iron and pure vanadium, were irradiated with metallic ions and subsequently subjected to instrumented indentation tests. The load-displacement property obtained from the experiment was analyzed in various schemes to extract the amount of the net hardening due to ion-irradiation.
