Contrary, only a few fatigue crack growth rate (FCGR) studies are available in the literature. Considering the above, LPBF manufactured IN718 is heat treated in variants including (H) and excluding (A) hot isostatic pressing. FCGR tests are performed at stress ratios R = 0.1 and R = 0.5. Both variants show similar FCGR and fracture modes at both stress ratios, despite a significant difference in ductility. Furthermore, A and H show similar FCGR at R = 0.1 and better performance at R = 0.5 compared to wrought IN718.
