Abstract
A method for the production of a γ-TiAl base alloy by vacuum arc remelting, which γ-TiAl base alloy solidifies via the β-phase (β-γ-TiAl base alloy), includes the following method steps of forming a basic melting electrode by melting, in at least one vacuum arc remelting step, of a conventional γ-TiAl primary alloy containing a lack of titanium and/or of at least one β-stabilizing element compared to the β-γ-TiAl base alloy to be produced; allocating an amount of titanium and/or β-stabilizing element to the basic melting electrode, which amount corresponds to the reduced amount of titanium and/or β-stabilizing element, in an even distribution across the length and periphery of the basic melting electrode; and adding the allocated amount of titanium and/or β-stabilizing element to the basic melting electrode so as to form the homogeneous β-γ-TiAl base alloy in a final vacuum arc remelting step.
