FIELD: metallurgy.
SUBSTANCE: invention relates to the field of metallurgy, namely to the production of light alloys based on aluminum, and can be used in the rocket and aerospace, aviation and automotive industries. Method of obtaining the dispersion hardened aluminum alloy includes filling the vessel with aluminum melt, while below the level of the molten metal lower the nozzle unit having at least one nozzle into which an oxygen-containing gas with an oxygen content of at least 20 % by volume is supplied through the lined supply system, the time and feed rate of which is chosen from the condition of saturation of the alloy given by the number of formed hardening particles of aluminum oxide.
EFFECT: invention is aimed at increasing the strength and wear resistance of alloys, as well as reducing costs for the production of dispersion-strengthened aluminum alloy.
