Deformation mechanisms activated during tensile deformation of nanocrystalline NiTi wire in martensite state were investigated by combination of two experimental methods: (i) analysis of the evolution of martensite-variant microstructures in grains of deformed wire by TEM and (ii) analysis of the evolution of martensite texture by in situ synchrotron X-ray diffraction. The obtained results are linked to the activity of various twinning processes in martensite.
