FIELD: metallurgy.
SUBSTANCE: method involves introduction to molten aluminium alloy of modifying additive and melt crystallisation; with that, as modifying agent, Al-Sc-Zr alloy combination is used, which contains 0.002-0.02 % Sc and 0.002-0.02 % Zr and which is introduced to the melt in the form of a rod prior to crystallisation.
EFFECT: limit crushing of grain structure of aluminium alloys, which allows obtaining ingots with non-dendrite structure.
