AA3104 can-body stock ingot: Characterization and homogenization

Abstract

In the work reported here, AA3104 can-body stock ingot was characterized for through-thickness variation in chemistry, microstructure, and secondary dendrite arm spacing. Various homogenization practices were simulated using samples from the edge and the center of the ingot to assess across-the-width variation. The study included measurement of the manganese content in solid solution and the evaluation of the α-Al12(FeMn)3Si dispersoid size distribution. A two-step homogenization practice resulted in the most coarse dispersoid size distribution, which is expected to lower the earing in the final gauge sheet.
