How does hydrogen behave in aluminum alloys?

Light, strong and abundant, #aluminum and its #alloys are widely used in #construction , consumer #electronics, and for vehicles including cars, ships, and #aerospace. In this video, Huan Zhao explores a phenomenon which results in the weakening of these materials, namely #hydrogen #embrittlement. Employing cryogenic-transfer atom probe tomography, Zhao is able to provide a three dimensional analysis of how hydrogen is located within the aluminum alloys’ #microstructure. Identifying grain boundaries as a key site for #hydrogenembrittlement, the research highlights possible strategies to both better understand and counteract material’s failure.
