Scandium is one of the most effective alloying components of aluminum alloys. A small addition of scandium (about 0.2 – 0.3%) facilitates an increase in strength properties of wrought semiproducts of aluminum alloys by 100 – 150 MPa, limited cast grain refinement (up to formation of as non-dendritic structure), a marked improvement in …

Scandium is the most potent strengthening element when added to aluminium. This means that only a very low amount of scandium is needed to provide significant strengthening effects, with an average yield strength increase of 50 MPa per 0.1 wt.%Sc addition . The fact that only small amounts are required means that the negative …

Alongside increased strength, adding scandium to an aluminum alloy also improves or stabilizes the material's ductility. This feature combines with aluminum scandium's strong resistance to recrystallization to enable the creation of superplastic alloys that can form at strain rates up to 10 − 2 s − 1.

It is shown that the addition of scandium considerably influences the structure and properties of aluminum and its alloys. Scandium is the strongest inoculant of the cast grain structure of aluminum alloys, the strongest suppressor of recrystallization, and the strongest hardener (per 0.1% of the additive). The addition of zirconium intensifies and …

Scandium also interrupts melted aluminum crystalizing at a molecular level when the metal cools. This means that the properties of the alloy are less likely to be affected by heat-treatment and welding, so a scandium-infused aluminum alloy is less likely to crack while cooling. This is especially valuable in high-strength aluminum, like …
