| Abstract Scope |
Aging studies for aluminum alloys traditionally focus on limited processing parameters (aging time or temperature), a slow and time-intensive process when evaluating multiple compositions. In order to optimize alloy design, we introduce a method to fabricate bulk samples using a combinatorial approach in sputter deposition. Within a single 150um thick foil, we can significantly vary chemical composition, allowing for faster discovery of promising chemistries. Here, we focus on the Al-Mg system, characterizing mechanical properties like hardness and tensile strength as a function of multiple aging times and temperatures for a range of chemistries. Through this methodology, we hope to accelerate discovery of a range of compositions that yield superior strength and stability at higher temperatures. |
