Mechanical properties of ion irradiated steel EK-181 investigated by dynamic nanoindentation
Abstract
Heavy ion irradiation is a unique tool that can be used to simulate and study radiation processes in materials. It can reproduce in a small near the surface layer various microstructural features (dislocation loops, precipitates, voids, etc.) observed in neutron-irradiated materials. Because the irradiation damage is restricted by a few micrometres near surface layer, mechanical properties investigation of the samples was carried out by dynamic nanoindentation technique. This method allows obtaining continuously the hardness and elastic modulus depth profile by one indent. Nanoindentation results acquired in this work showed increase in irradiated layer hardness caused by the increase in irradiation temperature and damage dose.
