[edit] Nugget A proxigram obtained from a LEAP tomographic dataset of a dilute Al-Sc-Lu alloy which has been aged at 300 deg C. Nanometer-sized Al3(Sc1-xLux) precipitates are exploited as a strengthening phase. This proxigram quantifies the core/shell structure which develops in the precipitates, with Lu segregating to the center of the precipitates and Sc forming a shell around the core.
