Selective laser melting (SLM) processed Inconel 625 exhibits outstanding mechanical properties, compared with the conventionally manufactured counterparts, and has been widely used in aeronautic and aerospace engineering. In this study, the fracture mechanism of SLM-processed Inconel 625 in different building directions was systematically characterized and analyzed using scanning electron microscopy (SEM) and energy dispersive spectrometer (EDS). The results reveal that the HIP treatments have a significant influence on the deformation and rupture behavior of the SLM-processed Inconel 625.
