چکیده
The largest amount of latent heat the martensitic transformation in nickel titanium shape memory alloy was explored. measured amounts alloys with different compositions between 48.0 at.% Ni and 51.0 were compared. \(-\) 37.8 J/g absorption 34.8 emission obtained as averaged values several samples equiatomic composition. These magnitudes are close to those novel storage ceramics, VO2 (51 J/g) Ti3O5 (60 J/g), suggesting NiTi is potential candidate for material.Graphical abstract

متن کاملOn the Damping Behaviour of Niti Shape Memory Alloy
Shape memory alloys exhibit a high damping capacity in the mktensite state. Results obtained from both DMA and cyclic tests under tension-compression load show that the martensite damping capacity in NiTi SMAs is a function of both strain amplitude and annealing temperature. Internal friction due to movements of martensite twin boundaries within both elastic (accommodation) and inelastic (reori...

متن کاملCrystallization kinetics of amorphous NiTi shape memory alloy thin films
The temperature dependence of the crystallite nucleation and growth rates is measured for amorphous NiTi thin films. Using transmission electron microscopy, crystallites are shown to nucleate homogeneously in the film and to grow in a channeling mode. A mechanism that suppresses heterogeneous nucleation is proposed. By manipulating nucleation and growth rates, grains as large as 60 lm can be ob...
