Results of a study of the structure, phase composition, and main parameters of high-temperature strength of forgings from deformed magnesium alloy VMD16 of the Mg – Zn – Zr – REE system in aged condition are presented. The distinctive features of alloy VMD16 responsible for the thermal stability and high-temperature strength of the alloy are determined, which make it superior to the commercial refractory alloy MA12. It is shown that thermally stable LPSO-phases are present in alloy VMD16 in the form of nanoplates in the bulk of grains and in the form of nanoblocks in multilayer fragments of the eutectic.
