METHOD FOR OBTAINING BASIC β-γ-TiAl-ALLOY Russian patent published in 2013 - IPC C22C14/00 C22B9/20 

FIELD: metallurgy.

SUBSTANCE: method involves the following stages: formation of a basic consumable electrode by melting with the help of at least one stage of vacuum arc melting of common primary γ-TiAl-alloy containing titanium and/or at least one β-stabilising element in the amount that is not enough in comparison to the obtained basic β-γ-TiAl-alloy, arrangement on the above basic consumable electrode of titanium and/or p-stabilising element in the amount corresponding to the above insufficient amount of titanium and/or β-stabilising element, with uniform distribution as to length and periphery of the basic consumable electrode, addition to the basic consumable electrode of the above arranged amount of titanium and/or β-stabilising element so that homogeneous basic β-γ-TiAl-alloy is obtained at final stage of vacuum arc melting process.

EFFECT: invention allows creating homogeneous basic β-γ-TiAl-alloy without formation of any cracks.
