High-Throughput Compositional Study of 3xxx Al Alloy Using Laser Synthesis and Small-Scale Rolling: A Case Study

The recyclingRecycling of 3xxx series alloysAlloys, often used to manufacture beverages, is undergoing the high demand to reduce energyEnergy consumption and carbon emission. A detailed understanding of the compositional effects (e.g., Mn, Fe, Si, etc.) on the mechanical propertiesMechanical properties is required due to the wide spectrum of alloyAlloys compositions received from the recycled alloysAlloys. We demonstrate a case study of using a newly established high-throughputHigh-throughput approach to establish the composition-property relationship of Al-Mn-Fe-Si-Cu alloysAlloys, involving combinatorial alloyAlloys synthesis by laser direct energyEnergy deposition (DED) additive manufacturingAdditive manufacturing (AM) and small-scale rolling. The study focuses on the effects of Mn and Si on precipitation and recrystallizationRecrystallization. The results reflected the similar behavior of DED alloysAlloys as DC-Cast counterparts in terms of microstructureMicrostructure and mechanical propertiesMechanical properties. This project suggests that the proposed methodMethod can support the material screening and phenomenological/mechanistic study for 3xxx series alloysAlloys.
