Query: Blocking of martensitic transition at the nano-scale in the Ti2NiCu
  wedge   Shape memory effect associated with martensitic transformations is of the
rapidly developing field in nanotechnologies, where industrial use of systems
established on that effect provide greater flexibility on the nano-devices
fabrication of various kind. And therefore it addresses questions to the phase
transition phenomena at low-scale and its limitations and control. In this
report, we studied the crystal structure of tapered plates of Ti$_2$NiCu alloy
and the temperature $T_c$ at which the martensitic transition occurs. We
demonstrated that $T_c$ has a strongly descending character as a function of
the plate thickness $h$. The critical thickness value at which the transition
completely suppressed is 20 nm. Moreover, the obtained results for $T_c(h)$
curves indicate the hysteretic nature of the transition. These findings open
the pathway for size limits indication and regimes modulation where the
alloy-based nano-mechanical devices can be tuned to operate more efficiently.
