METHOD OF MAKING CONDITIONING AGENT FOR HYPOEUTECTIC ALUMINIUM-SILICON ALLOYS

摘要

FIELD: process engineering.;SUBSTANCE: invention relates to metallurgy, particularly, to conditioning castable aluminium-silicon alloys of hypoeutectic composition. Rod-like modifying agent is made by mixing aluminium powder with particle size of 0.5-0.7 mm and superdispersed powder of titanium nitride with mean particle size of 40 nm in planetary-type mill for fine minutes at 400 rpm, and compacting produced composition into rod.;EFFECT: higher content of superdispersed powder of titanium nitride.;2 tbl, 1 ex
