    Abstract: The invention refers to a method for manufacturing a three-dimensional metallic article/component made of a Ni-, Co-, Fe-based superalloy or combinations thereof, entirely or partly, by a powder based additive manufacturing process. During the step of performing powder melting by scanning a dual laser setup is used, where two laser beams of different beam properties are combined in the same machine and by adjusted beam profiling and integration of a suitable beam switch in a controlled manner a switching between two different laser beam diameters is performed. In each layer the laser beam with the smaller diameter scans the whole area and in every kth layer, with k>1, the laser beam with the larger diameter scans the area where a coarse grain size is needed thereby remelting the area with fine grain sizes. With such a manufacturing method higher lifetime and operation performances of metallic parts and prototypes can be reached.

    Abstract: The invention relates to a method for manufacturing a component, especially for gas turbines and other thermo machinery. The method includes providing a data set defining the component for being used in an additive manufacturing process; manufacturing said component by means of said additive manufacturing process according to said data set; and subjecting said manufactured component to a heat treatment (HT) in order to change the microstructure of the manufactured component. The properties of the component are improved in that at least two different component volumes (CA1-CA3) are defined within said component prior to the manufacturing step; at least two different process parameters (A, B) are chosen for the additive manufacturing process, which process parameters (A, B) result in different driving forces for a recrystallization and therefore a different recrystallization behavior in the material of the component; and the additive manufacturing process is executed with one of the at least two process parameters (A, B) being used during manufacturing a first of the at least two component volumes (CA1-CA3), resulting in a first recrystallization behavior in the first component volume, and with the other of the at least two process parameters (A, B) being used during manufacturing a second of said at least two component volumes (CA1-CA7), resulting in a second recrystallization behavior different from said first recrystallization behavior, in the second component volume; and the manufactured component is subjected to a heat treatment (HT), with a holding temperature (T_HT), wherein the holding temperature (T_HT) lies above a recrystallization temperature of at least one of said at least two component volumes.
