Abstract

High-strength V-1963 alloy of Al–Zn–Mg–Cu system with small additions of zirconium, scandium and silver, developed by FSUE «VIAM», made for massive highly stressed parts (such as frames, fittings, beams, etc.) of primary structure of modern aviation engineering. Alloying with small additions of silver and scandium allowed to simultaneously increase the strength characteristics (by 10–20%), and fatigue resistance (1,8–2,3 times) in comparison with serial domestic and foreign alloys. Unlike the other high strength alloys of Al–Zn–Mg–Cu system, weldability characteristics of V-1963 were improved as compared to similar alloys without silver, and V-1963 also has an acceptable level of corrosion resistance characteristics. Within the terms of the federal target programs at FSUE «VIAM» and the implementation of an integrated scientific direction 8.1. «High-strength welded aluminum and aluminum-lithium alloys of low density with high fracture toughness» («Strategic directions of development
