METHOD OF PRODUCTION OF CAST ALUMINIUM-MATRIX COMPOSITE ALLOY Russian patent published in 2015 - IPC C22C1/10 

FIELD: metallurgy.

SUBSTANCE: invention relates to the metallurgy, namely, to production of cast aluminium-matrix composite alloys. The method includes aluminium melting, addition to the melt portions of exothermic charge containing titanium and carbon powders, melt mixing, at that prior to addition to the melt the exothermic charge is granulated using the binding agent being flux out of fluorine rubber with production of the granules 0.2-6.0 mm, and content of dry fluorine rubber 1-2%, the produced granules are added to the melt by portions in the aluminium foil with thickness 0.2-0.5 mm, after charge addition the melt is held for at least 5 minutes.

EFFECT: flux and artificial granulation use makes easier addition of the charge to the melt, increases degree of charge components recovery in the melt, and uniform distribution of the synthesised particles of the strengthening phase in the matrix alloy.
