FIELD: metallurgy.
SUBSTANCE: invention relates to production of a rolled product from nickel-titanium alloy. Method of producing nickel-titanium article by thermomechanical treatment involves cold treatment of workpiece from nickel-titanium alloy at temperature less than 500 °C and hot isostatic pressing of cold-processed billet of nickel-titanium alloy, wherein billet from nickel-titanium alloy contains at least 35 percent by weight of titanium and at least 45 percent by weight of nickel.
EFFECT: obtained articles are characterized by high strength and fatigue life.
