Abstract (en)

[origin: WO2011047937A1] The invention relates to a method for producing a ?-TiAl base alloy solidifying over the ß-phase (ß-?-TiAl base alloy) by means of vacuum arc remelting, having the following method steps: smelting a base smelting electrode (2) of a conventional ?-TiAl primary alloy having a deficit content of titanium and/or at least one ß-stabilizing element in respect of the ß-?-TiAl base alloy to be produced in at least one first vacuum arc remelting step, allocating a quantity of titanium and/or ß-stabilizing element corresponding to the deficit content of titanium and/or ß-stabilizing element to the base smelting electrode (2) in uniform distribution over the length and circumference thereof, and alloying the allocated quantity of titanium and/or ß-stabilizing element in the base smelting electrode to form the homogenous ß-?-TiAl base alloy in a final vacuum arc remelting step.
