Radiation‐Resistant Aluminum Alloy for Space Missions in the Extreme Environment of the Solar System (Adv. Mater. 20/2026)

Radiation-Resistant Aluminum Alloy for Space Missions In their Research Article (DOI: 10.1002/adma.202513450), Patrick Willenshofer, Matheus A. Tunes, and co-authors introduce a new ultrafine-grained aluminium crossover alloy designed for future long-duration deep space missions. Through atomic-level thermodynamic tailoring, the new alloy demonstrates unprecedented tolerance to extreme irradiation conditions, exhibiting no significant irradiation-induced hardening or embrittlement, enabling next-generation of lightweight spacecraft materials for solar system and extraterrestrial exploration.
