FIELD: technological processes.
SUBSTANCE: invention is related to manufacturing of ingots and cast articles out of intermetallic alloys based on titanium and aluminium. Method includes melting of initial charge in crucible and further crystallisation of melt in mold, made of aluminium nitride or lined with aluminium nitride inside, at that melt crystallisation is carried out in atmosphere of inertial gas, for instance argon with dew point of not more than minus 70° C.
EFFECT: improved quality of ingots and articles due to reduction of common oxygen content, and lower production costs.
