Abstract
The paper focuses on the study of the shape memory effect (SME) and two-way SME (TWSME) in nanostructured Ti-50.7 at.%Ni alloy. Two different types of structure were studied: nano-subgrain structure (after the moderate deformation with true strain e = 0.3) and nanocrystalline structure (after the severe plastic deformation with true strain e = 1.55). The homogenizing annealing at 700 deg, 20 min as well served as a reference heat treatment (RHT). In all cases isothermal annealing at 430-450 deg. was performed. The aging time, the initial phase state and external action parameters were varied. The SME training procedure was carried out under a bending mode; the constrained strain �0 t was varied from 3.9 to 25% and the loading time from 30 s to 3 min. Aging time, constrained strain and loading time strongly affect all studied SME and TWSME parameters. The combined effect of 10 h ± aging, loading through B2 R %��∂�WUDQVIRUPDWLRQDQG������I��
