Topics of modification of the grain structure and of formation of supersaturated solid solution in crystallization of melts of scandium-alloyed aluminum alloys are considered. The strong modifying property of scandium is a result of the effective inoculating action of Al3Sc particles and their great number in unit volume of the melt. Scandium is susceptible to formation of supersaturated solid solutions at enhanced crystallization rates, and an additive of zirconium intensifies this susceptibility.
