FIELD: metallurgy.
SUBSTANCE: jet of hydrocarbon gas is injected into alloy matrix melt during casting to produce fine carbide particles due to decomposition into carbon and hydrogen at temperature of melt and mixing the melt with said particles, as well and crystallising the casting. Said matrix alloy represent that based on aluminium, magnesium, iron, nickel, cobalt or chromium. Mixing said melt with formation of fine carbine particles is performed by surfacing bubbles of released hydrogen.
EFFECT: ruling out casting defects and higher quality.
