Al-Sc-Er.jpg

Al-Sc-Er alloy, with Sc atoms in purple and Er atoms in gold. The isoconcentration surfaces show that Er partitions to the core of the precipitate and Sc partitions to the precipitate shell. This is described further in Effects of Substituting Rare-Earth Elements for Scandium in a Precipitation-Strengthened Al 0.08 at.% Sc Alloy by Rick and Marsha.
