FIELD: metallurgy.
SUBSTANCE: modification of metals is performed with ultrafine powder (UP) in the form of mixture containing carbide-like phase FeAlCn, aluminium oxide Al2O3, and aluminium hydroxide Al(OH)3 with particle size of 102-103 nm; mixture is ground in constant magnetic field with intensity of 0.1-0.5 Tm and the obtained powder is introduced to molten metal.
EFFECT: invention allows improving quality of produced metal and cast products owing to reducing the size of particles of modifying agent powder.
