(EP3037194) The Invention concerns a Procedure for the Production of a Turbine (10) with a creepsteady Hub (20) and Shovels (31, 32, 33, 34 [duktilen]). This covers a Making of a Turbine (10) available with a Hub (20) and several Shovels (31, 32, 33, 34), which of an TiAl alloy consists, the 60 VOL. - % to 100 [Vol],% Grains with a full-laminated Structure from one α [2] - Phase ([Ti] [3] Al) and a γ-phase ([TiAl]) exhibits and besides Grains with other Phases to exhibit can, Would Drive Through a Thermal Treatment of the Shovels (31, 32, 33, 34), without accomplishing thereby a Thermal Treatment of the Hub (20), and a Receiving of the Turbine (10) with a creepsteady Hub (20) and [duktilen] Shovels (31, 32, 33, 34). A Turbine producible by means of this Procedure (10) a Hub (10) points up, which consists of an TiAl alloy, which 60 VOL. - % to 100 [Vol],% Grains with a full-laminated Structure from one α [2] - Phase and a γ-phase exhibit and besides Grains with other Phases to exhibit can, and it exhibits Shovels (31, 32, 33, 34), which consist of an TiAl alloy, which predominantly exhibits Grains with a fine-laminated Structure or a single-phase Structure. The Turbine (10) can be used in particular in a Supercharger.
