This study investigated the effect of laser scanning speed on the microstructure of Al₂O₃-GAP eutectic ceramics. Increasing the speed changed the morphology and successfully refined the minimum phase spacing to 62 nm at 10,000 mm/min. EBSD analysis confirmed two dominant crystallographic orientation relationships.
