Abstract

Especially strong aluminum alloys of experimental compositions are studied, wt.%: Al – (8.0–9.5) Zn – (1.6–2.2) Mg – (1.2–2.0) Cu – (0.08–0.15) Zr – 0.17 Sc – 0.24 Ag – (0.05–0.07) Ti – (0.03–0.04) Mn – (0.05–0.12) Fe – (0.01–0.02) Si. Heat treatment regimes are selected. The effect of alloying and artificial ageing regimes on the structure and properties of experimental alloys are determined. It is shown that especially strong alloys of the Al–Zn–Mg–Cu system after ageing by a single-stage regime (T1) exhibit maximum strength (σu up to 700 MPa). Two-stage softening regime of type T22 provides a high level of mechanical properties combined with satisfactory corrosion resistance.
