Abstract
The multi-component system interaction mechanisms associated with ultrafine powders (TiO2 and ZrO2) and fluorine-containing salts (K2ZrF6, Na3AlF6 and Na5Al3F14) with the Al-7%Si melt are studied. The formation of a multi-phase system with a high concentration of crystallization centres (N ≈ 7 · 1012 U/cm3) was identified. We experimentally show that the injection of an ultrafine powders modifying mixture containing refractory metal oxides and fluorine-containing salts into a Al-7%Si melt leads to a significant reduction in the a silicon plate size (by 1.5 times) and the Fe-containing phases (by 4 times). An equal distribution of the eutectic phase (α-Al + β-Si) is established in the Al- 7%Si alloy. As a result of microstructural changes when the modifying mixture was injected, a factor of 2 increase in the Al-7%Si alloy ductility was observed.
