Abstract
A process for the production of a body of material stable at high temperatures. In this process, the body of material is formed by solution annealing and subsequent precipitation hardening of a hot work-hardened starting body composed of an iron-nickel superalloy of the type IN 706 provided in a furnace. The body of material is distinguished by a particularly high ductility in combination with high hot strength if the solution-annealed starting body is cooled from the annealing temperature envisaged for the solution annealing to the temperature envisaged for the precipitation hardening at a cooling rate of between 0.5.degree. and 20.degree.
