| Summary: | This study examines how the microstructure and mechanical properties of the Laser
Power Bed Fusion (LPBF) AlSi10Mg alloy are affected by heat treatment parameters
such as cooling methods, solution treatment temperatures, and aging times. The rapid
solidification intrinsic to the LPBF process leads to a refined microstructure with much
higher hardness and strength than those of the alloy fabricated using the conventional
manufacturing (CM) method. The goal is to modify the microstructure of the LPBF
AlSi10Mg to match that of CM AlSi10Mg, while enhancing its mechanical properties.
According to the results, faster cooling methods improve grain refinement and hardness,
solution treatment homogenizes the microstructure and aging first increases the
hardness but eventually reduces strength. By adjusting these variables, a desired
balance of mechanical properties can be obtained, indicating that LPBF AlSi10Mg has
the potential to be a competitive substitute for conventionally manufactured alloy
