Abstract (en)

[origin: US2017081751A1] A method for producing a preform from an α+γ titanium aluminide alloy for producing a component with high load-bearing capacity for piston engines and gas turbines, in particular aircraft engines, by forging a blank, wherein the blank held in a manipulator and moved by the manipulator is subjected to merely partial forming by open-die forging by an open-die forging tool.

Abstract (de)

Verfahren zur Herstellung einer Vorform aus einer ±+³-Titanaluminid-Legierung zur Herstellung eines hochbelastbaren Bauteils für Kolbenmaschinen und Gasturbinen, insbesondere Flugtriebwerke, durch Schmieden eines Rohlings, wobei der in einem Manipulator (2) gehaltene und über den Manipulator (2) bewegte Rohling (1) durch Reckschmieden mittels eines Reckschmiedewerkzeugs (5) lediglich partiell umgeformt wird.
