Micro-Twinning in IN738LC Manufactured with Laser Powder Bed Fusion [PDF]

Materials, 2023
Components manufactured with Metal Laser Powder Bed Fusion (PBF-LB/M) are built in a layerwise fashion. The PBF-LB/M build orientation affects grain morphology and orientation. Depending on the build orientation, microstructures from equiaxed to textured grains can develop.
