| Abstract Scope |
This study examines the effect of high-energy laser beam shapes on the microstructure of Inconel 718 post-solution annealing as part of the EU project InShaPe. We utilized Gaussian, C-shape, and doughnut laser beams to observe variations in grain size, phase distribution, and defect density before and after solution annealing. Microscopy techniques revealed that beam shape significantly influences microstructural development and determines which phases correlate to various mechanical and corrosion properties. Our findings emphasize the critical role of laser beam shape in optimizing solution annealing processes to achieve desired material properties, enhancing the performance and stability of the components. |
