Structurally complex phase engineering enables hydrogen-tolerant Al alloys

Nature, Published online: 30 April 2025; doi:10.1038/s41586-025-08879-2A size-sieved complex precipitation in Sc-added Al–Mg alloys achieves a high-density dispersion of both fine Al3Sc nanoprecipitates and in situ formed core-shell Al3(Mg, Sc)2/Al3Sc nanophases with high hydrogen-trapping ability.
