In this work, an innovative heat treatment process was investigated for a nickel-based superalloy, which is manufactured by Laser Powder Bed Fusion (PBF-LB). These alloys require Hot Isostatic Pressing (HIP) as a post-processing step, which involves the simultaneous application of high temperature and high isostatic gas pressure with the aim to achieve a defect-free component. Typically they also require the subsequent heat treatments (such as annealing or aging) to be performed in a separated low- pressure furnace. In contrast, the new approach, here explored, allows to run both the HIP and the solution treatment within a single processing stage in a single furnace.
