FIELD: technological processes.
SUBSTANCE: invention relates to metallurgy and can be used during monocrystalline articles casting, for example, gas turbine engines turbine working blades with preset crystallographic orientation. Method involves production of billets stubs having cylindrical shape by casting. During casting on billet generatrix along cylinder axis marks are made in form of one or two diametrically arranged ledges or slots. Performing cast pieces crystallographic analysis, selecting billets, on which position of marks is aligned with billet structure azimuthal crystallographic direction, and performing selected billets cutting for stubs.
EFFECT: higher accuracy of casts stubs orientation, stubs production lower labor input.
