Method for the production of a highly stressable component from an α+γ-titanium aluminide alloy for reciprocating-piston engines and gas turbines, especially aircraft engines

PROBLEM TO BE SOLVED: To provide a method for production of a highly stressable component from an α+γ- titanium aluminide alloy.SOLUTION: There is provided the method for production of a highly stressable component from an α+γ- titanium aluminide alloy for a reciprocating-piston engine and a gas turbine, especially an aircraft engine. The alloy used is a TiAl alloy having a composition containing, by atom%, Al:40 to 48%, Nb:2 to 8%, at least one kind of β-phase-stabilization element selected from Mo, V, Ta, Cr, Mn, Ni, Cu, Fe, Si:0.1 to 9%, B:0 to 0.5% and the balance Ti and smelting-related impurities, wherein deformation is carried out in a single stage starting from a preform with a volume distribution varying over the longitudinal axis, wherein the component is deformed isothermally in the β-phase region at a logarithmic deformation rate of 0.01 to 0.5 s.SELECTED DRAWING: None
