Abstract: The process serves 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 ironnickel 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 and 20 ¢.degree.C/min!.

Abstract: The iron-aluminum alloy comprises the following constituents in atom percent: -12-18 aluminum -0.1-10 chromium -0.1-2 niobium -0.1-2 silicon -0.1-5 boron -0.01-2 titanium -100-500 ppm carbon -50-200 ppm zirconium - remainder iron. - This alloy is distinguished by high thermal-shock resistance and, at temperatures of 800 DEG C., still has comparatively good mechanical properties. The alloy can be used advantageously in components such as, for example, casings of gas turbines, which, with comparatively low mechanical loading, are subject to frequent thermal cycling.
