A 3D‐Printed SFE‐Graded Alloy Mitigates Cryogenic Discontinuous Plastic Flow and Hydrogen Embrittlement
ABSTRACT The lunar polar permanently shadowed regions, rich in water ice for hydrogen production, impose a trade‐off in FCC alloys: lowering stacking‐fault energy (SFE) enhances hydrogen embrittlement resistance but exacerbates cryogenic discontinuous plastic flow (DPF). To address this, we designed and fabricated via...
