Four high entropy alloys (HEA), CoCrCuFeNi, Co1.5CrFeNi1.5Ti0.5Mo0.1, both adopting an FCC structure, and TaNbHfZrTi, and AlCoCrFeNiSi, adopting a BCC structure, have been irradiated with He and 3 MeV Ni ions, as part of the process of understanding their application within fission based nuclear reactors.When irradiated nano-indentation analysis shows that the FCC and BCC respond differently. The FCC phases show a decrease in hardness with increasing ion fluence, for example at depth of 100nm CoCrCuFeNi shows a decrease from ~7.5 GPa to ~4.5 GPa. However, the BCC phases show an initial increase in hardness with ion fluence, for example at a depth of 100nm TaNbHfZrTi, shows an intial increase from ~9.5 GPa to ~ 10.2 GPa, with a subsequent drop to ~8.75 GPa.Transmission electron microscopy based analysis shows that ion beam induced damage is visible in the samples, with 3 MeV Ni inducing differing levels of visible damage. Analysis of He irradiated samples suggests that there might be beginnings of bubble formation, but the evidence is not clear cut.
