We firstly revealed the texture from macroscale of an additive manufactured Co-Cr-Mo alloy, which was produced by laser-based powder bed fusion (PBF-L) using a hatch rotation of 72° between the layers. The results show that the texture observed from the local area (microscale) was superposed. Furthermore, the overall bulk texture (macroscale) is not a simple algebraical sum of individual layers. The Goss texture component was observed in bulk. Instead of 5-fold symmetry texture in bulk, the texture is orthorhombic/tetragonal symmetry. Since this phenomenon occurs due to the manufacturing parameters, which shows the potential that the texture of PBF-L alloys can be tuned for optimizing the microstructure and properties.
