Abstract
The method serves to produce a material based on a doped intermetallic compound. In carrying out the method, at least two differently doped powders each based on the intermetallic compound are selected. One of the two powders predominantly has coarse-grained particles. On the other hand, another powder is formed from comparatively fine-grained particles composed of a material having a lower creep strength but a higher ductility than the material of the coarse-grained powder. The at least two powders are mixed with one another in a ratio serving to establish a desired mixed microstructure and then hot-compacted and heat-treated to form the material. Material produced by this method is suitable for components which are exposed to high mechanical loads at high temperatures, such as, in particular, gas-turbine blades or turbine wheels of turbo chargers.
