The regularities of influence of the recrystallized grain of the В2—austenite of the aging Ti—Ni alloy on the morphology, sizes and distribution of Ti3Ni4 phase particles formed during the process of the isothermal aging were established.
The regularities of influence of the microstructure of releases formed during the process of the isothermal aging in the recrystallized grain of the В2—austenite of various sizes on the staging of martensitic transformations were revealed. The conditions of changes to the staging of martensitic transformations related to the evolution of the structure and increase in the duration of aging were determined.
Special aspects of functional features of the aging Ti—Ni alloy with various sizes of the recrystallized grain, size and morphology and nature of the allocation of Ti3Ni4 [4,5] phase particles were discovered.
Special aspects of influence of the size of structural elements of the mixed nanograin / nanosubgrain structure and the size of grain of the В2—austenite in the recrystallized structure on functional features of the form-restoration of the Ti-Ni alloy were identified.
The scheme of the temperature-deformation application of the shape memory effect providing for the best complex of functional features was developed.
