Highlights
High-entropy alloys (HEAs) have attracted significant research interests due to their excellent strength, ductility, and radiation resistance [1, 2, 3, 4, 5, 6]
Fan et al [22] showed that void growth can be suppressed at relatively low doses, substantial void growth can occur after an incubation dose of ∼123 dpa under full cascade mode in NiCoFeCr irradiated by 3 MeV Ni-ion irradiation at 500 °C
A previous work by Fan et al [22] studied detailed dislocation and void evolution in NiCoFeCr with respect to temperature and dose, and our current work mainly studies the matrix concentration variation associated with preferential diffusion in irradiated NiCoFeCr
Summary
High-entropy alloys (HEAs) have attracted significant research interests due to their excellent strength, ductility, and radiation resistance [1, 2, 3, 4, 5, 6] These superior properties make HEAs suitable for a variety of applications, especially as potential structural materials for advanced nuclear energy systems [7, 8, 9, 10]. The underlying mechanism leading to the unusual distribution of voids at low doses remains unclear Uncovering this mechanism may explain the dramatic transition of void growth with dose and reveal in what HEA systems the transition could happen
