The formation of the Co-Ni-Nb alloy structure under superplastic deformation and phase composition is studied in the article. Investigations of the changes in the true stresses during superplastic deformation in the optimal mode of the dispersion-hardening alloy on a cobalt–nickel-niobium basis are carried out. The structure change at various degrees of deformation is studied. The features of structural transformations under superplastic deformation are analyzed. The evolution of the secondary phase and the change in the chemical and phase composition are considered as a result of the motion of the shear transformation zone.
