FIELD: metallurgy.
SUBSTANCE: exothermic mixture of aluminium and titanium powders is prepared, then it is subjected to mechanical activation. Simultaneously briquettes of the pressed titanium chips are made. Mixture of powders and briquettes of the pressed titanium chips are simultaneously added to aluminium melt, its surface has cryolite, the melt is held for at least 30 minutes with periodic agitation. Ratio of stoichiometric mixture of powders and briquette of titanium chips is selected as 1/3 of powders mixture to 2/3 of titanium chips.
EFFECT: invention increases quality of the alloy, improves its structure and uniformity of titanium distribution in the alloy volume, excludes slug inclusions and segregation zones combined by intermetallic compounds Al3Ti.
