摘要：
Two principles of alloying are suggested for creation of aluminum alloys sparingly alloyed with scandium, which intensify the metastability of the process of crystallization in continuous casting of ingots. The first principle consists in keeping a one-to-one scandium-to-zirconium proportion, for example, 0.11% Sc and 0.11% Zr. The second principle consists in multicomponent alloying with transition and rare-earth metals, which intensifies the metastability of crystallization.
