An initially single phase high entropy alloy (HEA) Al0.3CoCrFeNi was irradiated by 3 MeV Au ions to a fluence of 6 × 1015 cm−2 (∼31 dpa at damage peak) at four different temperatures ranging from 250 °C to 650 °C. Transmission electron microscopy (TEM) and Atom probe tomography (APT) were employed t...
