    Abstract: 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). It refers to a Nickel-base superalloy powder, wherein the superalloy powder has a chemical composition that allows establishing a gamma-prime precipitation content of 60-70 vol.-% in the superalloy in a heat treated condition. The powder has a powder size distribution between 10 and 100 μm and a spherical morphology. The ratios of the content (in weight-%) of the alloying elements C, B, Hf, Zr, Si are the following: C/B=10-32; C/Hf>2; C/Zr>8; C/Si>1. A preferred embodiment includes of the following chemical composition (in weight-%): 7.7-8.3 Cr; 5.0-5.25 Co; 2.0-2.1 Mo;7.8-8.3 W; 5.8-6.1 Ta; 4.7-5.1 Al; 1.1-1.4 Ti; 0.08-0.16 C; 0.005-0.008 B; 0-0.04 Hf;0-0.01 Zr; 0-0.08 Si; the remainder being Ni and unavoidable impurities.

    Abstract: The invention refers to a method for manufacturing a hybrid component including the following steps of manufacturing a preform as a first part of the hybrid component, then successively building up on that preform a second part of the component from a metallic powder material by means of an additive manufacturing process by scanning with an energy beam, thereby establishing a controlled grain orientation in primary and in secondary direction of at least a part of the second part of the component. The controlled secondary grain orientation is realized by applying a specific scanning pattern of the energy beam, which is aligned to the cross section profile of the component or to the local load conditions for the component.
