The Self-accommodated and reoriented martensites are assumed to deform elastically in levels I and III. This condition-of-the-art check out of NiTi deformation, even though it is extensively spread in the literature, is not in line with the outcomes of TEM and X-ray diffraction research on nanocrystalline NiTi wire presented over. https://www.ortix.co.uk/wires/
