Abstract (en)
[origin: EP2295608A1] ALUMINIUM-BASED GRAIN REFINER, which contains zinc, titanium and carbon, synthesized by means of aluminium fusion and the subsequent addition of titanium, zinc and carbon. The microstructure of the master alloy is comprised by an alpha-aluminium matrix, intermetallic phase of TiAl 3 and fine particles of a ternary compound of titanium-zinc-carbide. The titanium content is at least 1% and at the most 20%, the carbon content is at least 0.01% (100 ppm) and at the most 3% and the zinc content is equal to or over 1%.
