Abstrakt: We have carried out complex studies of the structure and properties after thermal hardening by the T1 mode of pressed shapes 20–40 mm thick from a new promising high aluminum alloy V-1977 based on the Al–Zn–Mg–Cu system with the addition of Zr. It has been found that, after aging according to the T1 mode, in the pressed shapes of alloy V-1977, a homogeneous structure and a uniform distribution of finely dispersed nanocrystalline particles of the η' phase and dispersoids of the β' phase (ZrAl3) with spherical shape are observed. Owing to this, the required level of mechanical, corrosion, and resource characteristics for parts of modern aviation and missile technology is achieved. Thus, the V-1977 alloy is shown to be competitive in comparison with the widespread serial alloy V95och and a domestic analog of alloy V96ts-3pch. [ABSTRACT FROM AUTHOR]
