WAYS FOR IMPROVING THE PROPERTIES OF SEMIPRODUCTS FROM V96Ts-3-TYPE HIGH- STRENGTH ALUMINUM ALLOYS OF THE Al — Zn — Mg — Cu SYSTEM

摘要

The effect of different modes of three-stage aging on the structure and properties of hot-deformed semiproducts (pressed shapes and rolled plates) from high-strength aluminum alloy V96Ts-3 of the Al - Zn -Mg - Cu system is studied with the aim of optimizing the hardening heat treatment. A mode of three-stage aging convenient for commercial production and ensuring hot-deformed semiproducts from alloy V96Ts-3 with high strength at the state T1 level in combination with satisfactory corrosion resistance corresponding to state T2 is suggested.
