The initial microstructure of the alloy consists of a fine lamellar α + β microstructure where α lamellae are separated by thin continuous β layers within prior β grains. The anisotropy of the alloy is studied in the deformation direction using samples that are built at the angles of 0°, 45°, and 90° with respect to the LPBF base plate. The sample oriented at 0° presents higher strength–ductility trade-off compared with the conditions oriented at 45° and 90°. The in situ HEXRD experiments continuously reveal the microstructure response during deformation and that the textures for each orientation are associated with a different activation sequence of deformation mechanisms.
