To achieve the goal set in the objective the compositions of 3 systems were under investigation: Zr-Ni-Fe-Ti, Zr-Ni-Cu-Ti и Zr-Ni-Co-Ti. Three-dimensional approximation of the reverse martensitic transformation As, depending upon cobalt (replacing nickel) and titanium (replacing zirconium) content, and two-dimensional topogram for the definition of the compositions with the reverse transformation temperature of 700°С were built with the use of the experimental data obtained. It allowed choosing required compositions of Zr-Ni-Co-Ti system with different titanium and cobalt content but the same temperature of the reverse martensitic transformation (700°С). At the final testing of alloys of Zr-Ni-Co-Ti system the basic composition of 44Zr-30Ni-20Co-6Ti (аt.%) alloy, which at accumulated deformation of 5% demonstrates 3.2% of the recoverable (reversible) martensitic deformation in 700 ? 900°С temperature interval. Patent search of the multi-component Zr-based high temperature shape memory alloys was carried out. Product Description popup.authors Коваль Ю.М. Кудрявцев Ю.В. Мусієнко Р.Я. Неганов Л.М.
