Due to its low density, high strength, and abundance, aluminum and its alloys are widely used for example in constructions, consumer electronics and for vehicles including cars, ships, trains and planes. However, aluminum alloys are prone to hydrogen embrittlement causing catastrophic failure during service if not noticed early enough. Compared to steel, the effects of hydrogen in aluminum are not well understood. Dr. Huan Zhao, postdoctoral researcher at the Max-Planck-Institut für Eisenforschung (MPIE), and her colleagues analyzed how hydrogen embrittles aluminum alloys and found first approaches of hindering this effect. The scientists have now published their latest results in the journal Nature.
