Аннотация: One of the ways to improve the mechanical and technological characteristics of aluminum alloys is to introduce modifiers into them, which are divided into two fundamentally different groups. Modifiers of the first kind, which have proven themselves to be positive, include elements such as Ti, Zr, B, Sb. Their addition to the alloy is up to 1% (wt.). Recently, studies have been conducted on the use of powder modifiers: boron carbide, silicon carbide, nitride or titanium carbide and other modifiers. Modifiers of the second kind include sodium, potassium and their salts. The disadvantage of these low-melting modifiers is that after processing the melt with them, the modification effect disappears after 30-40 minutes due to evaporation and oxidation of sodium. © Published under licence by IOP Publishing Ltd.
