Abstract

The article presents and summarizes data on the modification of cast aluminum alloys. In addition to the use of standard modifiers such as sodium, strontium, titanium, zirconium, scandium and titanium diboride, a positive effect of europium and hafnium on alloys has been shown. Despite the fact that many effective modifiers belong to the rare earth elements (REE), not all REE have a strong effect. The introduction of metals such as ytterbium and erbium into aluminum alloys had almost no effect on the morphology and size of the microstructure.
