Abstract
The results of studies of inelastic reversible strains and degree of shape recovery in samples of Ti49.3Ni50.7 (at %) alloy depending on the test temperature and phase state were presented. It is shown that high values of inelastic reversible strain in the absence of plastic deformation were observed in samples with the initial martensite structure B19′, two-phase structure B2 + B19′, and with the structure of high-temperature B2 phase. The influence of correlation of the yield stress and martensite shear stress on the manifestation of reversible inelastic strains and the development of plastic deformation was discussed.
