Zusammenfassung: | The application relates to the technology of producing three-dimensional articles by means of powder-based additive manufacturing, such as selective laser melting (SLM) or electron beam melting (EBM). Especially, it refers to a Nickel-base superalloy powder on basis of Hastelloy X consisting of the following chemical composition (in wt. -%): 20.5-23.0 Cr, 17.0-20.0 Fe, 8.0-10.0 Mo, 0.50-2.50 Co, 0.20-1.00 W, 0.04-0.10 C, 0-0.5 Si, 0-0.5 Mn, 0-0.008 B, remainder Ni and unavoidable residual elements and wherein the powder has a powder size distribution between 10 and 100 µm and a spherical morphology and the ratio of the content (in wt.-%) of alloying elements C/B is at least 5 or more. |
