Additive manufacturing (AM) of aluminum alloys represents a growth area in the Light Metals industry. Initially, AM aluminum alloy research was largely dominated by wrought aluminum alloys, especially Al-Si alloys with limited mechanical performance. Recent advancement in AM alloy design, which leverages the unique AM processing capability, creates exciting opportunities to design and deploy high-performance, heat-treatable AM aluminum alloys. A thorough understanding of the response of these alloys under different heat-treatment conditions is crucial for alloy optimization. Our recent work utilizing a world-leading synchrotron X-ray scattering facility has provided critical structural transformation insight for several AM aluminum alloys, including heat-treatable 5000 series aluminum alloys, customized 7000 series aluminum alloys, and custom-designed Al-Sc-Mn alloy with some best mechanical performances among AM aluminum alloys. We will highlight how our findings guide alloy optimization and underscore the impact of these characterization capabilities on the broad Light Metals community.
