Building on the previously discussed principles of radiation-induced damage to metals and the background related to the feasibility of repair, there are now several practical examples of successful repair of such damage, covering both laboratory research and engineering applications. An example is the electrical pulse repair of nickel-based alloys; a study published in npj Materials Degradation in 2026 showed that treating nickel-based alloys with high-current-density electrical pulses can significantly reduce the density of helium bubbles and dislocation loops caused by radiation, alleviate radiation-induced hardening, and avoid the problem of microstructural coarsening resulting from conventional thermal annealing, thereby enabling effective repair of radiation damage in nuclear components. Example of self-repair in nanotwinned copper: In-situ experiments published in Nature Communications in 2015 demonstrated that nanotwinned copper with pre-introduced nanoholes could rapidly capture and eliminate radiation-induced defects through high-density twinning boundaries; as the nanoholes were gradually eliminated, the material underwent self-repair, thereby significantly enhancing its resistance to radiation. Examples of NASA spacecraft hardware repairs: In 2023, NASA carried out an \"annealing process\" on the camera of the Juno Jupiter probe. By precisely heating the damaged silicon-based electronic components, it was possible to repair the damage caused by intense radiation, restoring the camera’s resolution to its levels from the time of launch and ensuring the successful completion of tasks related to imaging Io. Case of carbon nanotube-reinforced metal self-repair: Metal composites embedded with carbon nanotubes can utilize one-dimensional transport networks to remove helium gas generated by irradiation-induced transmutation, thereby preventing embrittlement caused by the accumulation of helium bubbles. This allows the material to maintain its structural integrity even after prolonged irradiation, enabling dynamic repair of damages during operation. These cases demonstrate the effectiveness of different technical approaches in repairing metal damage caused by irradiation, and some of these solutions show potential for application in practical engineering scenarios such as the nuclear industry.
