A feature of martensite transformation in intermetallic alloys does not allow finding the optimum composition of the developed alloy by calculation. Therefore, it was possible to determine the influence of each of them on the alloy thermomechanical properties and find the composition of the new alloy for medial applications(at.%): Ti (44.0-45.45), Ni (54.0-55.38), Co (0.15-0.25), Fe (0.06-0.15), Ta (0.08-0.15), Ag(0.03-0.10), Y(0.01-0.020) only based on numerous experiments with variation of alloy components and their partial quantity, for which composition Patent of Ukraine #94009 was granted. Sample testing for thermoelasticity was used to determine the modes of heat treatment of this alloy, which ensure maximum mechanical characteristics, namely: hardening temperature of 1223 K, annealing temperature of 883 K, annealing time from 3 up to 8 min.
