FIELD: metallurgy.
SUBSTANCE: aluminium-titanium-boron master alloy for modification of aluminium and its alloys contains at least 90 wt % of titanium diboride particles and not more than 10 wt % of particles of titanium aluminide or aluminium boride, at that, the ratio of titanium to boron in the master alloy is (1.918-2.356): 1.
EFFECT: reduced consumption of titanium-containing alloying additive, increased modifying ability of the master alloy and physical and mechanical properties of modified aluminium.
