FIELD: metallurgy.
SUBSTANCE: method for producing a blank of Ti49, 3Ni50, 7 nanostructured alloy with shape memory effect includes uniform angular pressing with accumulated degree of deformation more than 4 in the temperature range 300-550°C, plastic deformation and annealing. The blank produced after ECAP is enclosed in steel shell, and plastic deformation is carried out by free upsetting to degree of not less than 30% in temperature range of 20-300°C, then the blank is removed from the shell, and annealing is carried out at temperature T = 200-400°C.
EFFECT: enhanced mechanical properties and functional characteristics with the necessary cross-section of blanks.
