FIELD: aluminum-based alloy metallurgy, in particular superplastic sheet from high strength alloys based on Al-Zn-Mg-Cu-Zr system.
SUBSTANCE: claimed method includes ingot providing, pressed feed production in form of band with elongation ratio of at least 8 at 370-4500C, hot rolling and cold rolling with deformation degree of at least 30 %. In particular embodiment of the invention hot rolling is carried out at 370-4300C. Product made from claimed superplastic sheet is also provided (e.g., construction material for space- and aircraft, as well as instrumentation and transport).
EFFECT: superplastic sheets with improved strength characteristics.
