Abstract Scope Al-9Cu-6Ce and Al-9Cu-6Ce-1Zr (wt%) alloys were designed and produced with laser powder bed fusion additive manufacturing (AM) for high-temperature applications in 250 – 400 C temperature range. During AM, the thermal history varies from one location to another inside a melt pool which can result in heterogeneous microstructures. We will describe microstructural heterogeneities present at different length scales and their impact on monotonic tensile deformation in AM Al-Cu-Ce and Al-Cu-Ce-Zr alloys. The results show that the heat-affected zones underneath the melt pool boundaries are potential failure zones in the heterogeneous microstructure particularly under the condition of low strain-rate sensitivity. The addition of Zr enables age-hardening in Al alloys through the formation of nanoscale Al3Zr precipitates. The deformation behavior of the Al-Cu-Ce-Zr alloy in the presence of Al3Zr precipitates will also be discussed with implications for future alloy design.
