    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.
