Abstract
The 6xxx-series aluminum alloys are used for automotive production due to their high specific strength and ability to be manufactured into complex shapes via extrusion or stamping. Small additions of Cr and Mn are dispersoid formers added to improve recrystallization resistance and decrease peripheral coarse grain growth during extrusion. Replacing Cr and Mn with Sc and Zr maintains the recrystallization resistance while decreasing peripheral coarse grain volume, which increases the yield strength and ultimate tensile strength while maintaining ductility in a peak-aged extrusion.
