| Abstract Scope |
The current alloy development cycle of Aluminum alloys is lengthy and costly. This study evaluates the feasibility of using combinatorial materials synthesis and compositionally graded specimen design to accelerate the Al alloy discovery. The high-throughput exploration of the compositional space was enabled through an integrated experimental approach involving powder mixing and laser direct energy deposition additive manufacturing (AM). The concept was demonstrated in (1) Al-Mn binary alloys and (2) Al 3104 alloy, with the benchmarking against their cast counterparts. The research highlights the difference between AM and as-cast Al alloys, including grain structure, defect formation, second-phase particles, and mechanical properties. Besides the effects of alloy composition, the distribution and size of second-phase particles and their influences on the recrystallization during homogenization and rolling heat treatment were studied in detail. It suggests that the laser AM can develop a valid dataset to support the high-throughput material screening for Al alloys. |
