Prototypic Lightweight Alloy Design for Stellar‐Radiation Environments

Advanced Science, 2020
The existing literature data shows that conventional aluminium alloys may not be suitable for use in stellar‐radiation environments as their hardening phases are prone to dissolve upon exposure to energetic irradiation, resulting in alloy softening which
