Alloy 625 (UNS N06625) is a favorable candidate for additive manufacturing because of its excellent weldability and is used in the aerospace and chemical process industries. In this research the effect of various heat treatments (i.e., annealing, hot isostatic pressing, and solutionizing) on the microstructure and corrosion behavior of laser powder bed fusion manufactured Alloy 625 was studied. Test coupons were electrochemically characterized in accordance with ASTM G59 and ASTM G61 protocol in a 1 N sulfuric acid solution. Microstructural characterization was performed using optical and scanning electron microscopy (SEM), X-ray diffraction (XRD), energy dispersive spectroscopy (EDS) and electron backscatter diffraction (EBSD). The results of the electrochemical and microstructural characterization will be presented and discussed.
