    摘要: In a process for producing a large single-crystal component or directionally solidified component made of a nickel-based superalloy, the component is first cast into shape in a known manner to form a microstructure comprising dendrites, and then solution annealing for homogenizing the cast microstructure of the component and two-stage precipitation heat treatment are carried out. In order to avoid chemical inhomogeneities and internal stresses caused thereby, a HIP process with a pressure of higher than 160 MPa is carried out following the solution annealing.

This steel is distinguished, as compared with commercial steels, by a greatly improved creep behavior at temperatures of 550° C. and above. Moreover, it has an improved resistance to embrittlement during long-term aging and comparatively high toughness. The steel is advantageously used as a material for gas turbine rotors which are exposed to high inlet temperatures in order to increase the efficiency of the gas turbine, but is also used for steam turbines.
