The object of this study is the characterization of a nickel superalloy, Inconel 939, processed by Laser Powder Bed Fusion (LPFB), an Additive Manufacturing (AM) technique. This kind of metallic material finds its application in crucial fields such as the aerospace sector and energy production, particularly in the production of turbine blades. Here the specific properties required for the service, such as mechanical stability at high temperatures, meet those of nickel superalloys. Whitin this group of materials, IN939 has excellent mechanical characteristics and resistance to corrosion and oxidation at high temperatures. However, Ni superalloys exhibit high melting temperature, low castability and forgeability.
