The aging kinetics, the mechanical properties, and the structure of cast alloy IMV7-1 of the Mg – Y – Gd – Zr system alloyed additionally with dysprosium are studied. It is shown that yttrium and gadolinium may be replaced partially with dysprosium without changes in the aging kinetics and lowering the hardening and the level of the mechanical properties of alloy IMV7-1.
