ABSTRACT:
A process for producing coarse, longitudinally oriented column crystals with improved temperature change resistance and ductility in the transverse direction in a workpiece of any cross-section from an oxide-dispersion-strengthened nickel-base superalloy, which exists in fine-grained form, by annealing in the temperature range between 1000.degree. and 1200.degree. C., cooling to room temperature and isothermally annealing for coarse grain in the range between 1230.degree. C. and 1280.degree. C.
