The Self-accommodated and reoriented martensites are assumed to deform elastically in phases I and III. This state-of-the-artwork perspective of NiTi deformation, even though it is broadly unfold in the literature, just isn't according to the effects of TEM and X-ray diffraction experiments on nanocrystalline NiTi wire offered above.
