Nanoscale structural evolution of Al3Sc precipitates in Al(Sc) alloys
TL;DR: In this article, the exact morphologies of the Al3Sc precipitates were determined for the first time by HREM, in Al-0.1 wt% Sc and Al- 0.3 wt % Sc alloys, with 26 facets, which are the 6 {100} (cube), 12 {110} (rhombic dodecahedron), and 8 {111} (octahedron).
