The influence of the laser scan strategy on grain structure and cracking behaviour in SLM powder-bed fabricated nickel superalloy
TL;DR: In this paper, the authors used optical and SEM micrographs to show the observed grain structure in the SLM fabricated and Hot Isostatically Pressed (HIPped) material and found that the repeating pattern shown in the grain structure has been linked to the overlapping of the "island" pattern used as standard in the Concept Laser M2 powder-bed facility.
